Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. A doctor can tell you by video whether you are still protected and may prescribe emergency contraception; a copper IUD is fitted in person.
- Combined pill: one pill up to 48 hours late: take it and carry on, you are still protected. 2 or more missed: take the last one, use condoms for 7 days, and check whether you need emergency contraception.
- Mini pill windows: a traditional progestogen-only pill is late after 3 hours, desogestrel after 12 hours and drospirenone after 24 hours.
- Sickness: vomiting within 3 hours of a combined pill, or severe diarrhoea for more than 24 hours, counts as a missed pill.
- Emergency: call 112 for sudden, sharp pain low in the tummy with fainting or feeling very unwell, especially with a positive pregnancy test.
If you have had unprotected sex after missed pills, do not wait: emergency contraception works best the sooner it is taken, and you can get it from a pharmacy. Call 112 or go to an emergency department for sudden, severe pain low in the tummy with fainting or a positive pregnancy test.
Can an online doctor help after a missed pill?
Yes, usually. What to do after a missed pill depends on the type of pill, how late it was, where you are in the pack and when you had sex. A doctor can work this out with you by video, tell you whether you need emergency contraception, condoms or a pregnancy test, and may prescribe emergency contraception or a method that is easier to remember. A copper IUD, when it is the best emergency option, is fitted in person.
How an online consultation helps after a missed pill
- The rule for your pill: Combined, traditional progestogen-only, desogestrel and drospirenone pills each have different rules.
- Emergency contraception, if needed: Which kind, how soon, and how it affects restarting your pill.
- How long to use condoms: From 48 hours to 7 days, depending on the pill and the week of the pack.
- A method that fits your life: If pills keep getting missed, the patch, ring, implant or a coil may suit you better.
What the doctor checks after a missed pill
The doctor asks about anything urgent first, then about the facts that decide what you need. The doctor asks about:
- Warning signs: tummy pain, unusual bleeding, or a pregnancy test that is already positive.
- Your pill: the name of the pill or its ingredients, so the right rule is used.
- What happened: how many pills were missed or late, and by how many hours.
- Where you are in the pack: the week, and whether you started the pack late after the break.
- Sex: when you last had unprotected sex, including in the break between packs and the week before.
- Anything else: vomiting, diarrhoea, new medicines, and earlier missed pills in the same pack.
Before the call, have your pill packet or its leaflet to hand, so the doctor can see the ingredients and where you are in the pack.
How many hours late counts as a missed pill?
It depends on the pill. Check the ingredients on the packet: the window is counted from the time you usually take it.

| Type of pill | It counts as missed when it is | Extra contraception after a missed pill |
|---|---|---|
| Combined pill (oestrogen and a progestogen) | More than 24 hours late; 2 or more missed when more than 48 hours late | None for 1 missed pill; 7 days for 2 or more |
| Traditional progestogen-only pill (levonorgestrel or norethisterone) | More than 3 hours late (more than 27 hours since the last pill) | 48 hours |
| Desogestrel progestogen-only pill | More than 12 hours late (more than 36 hours since the last pill) | 7 days |
| Drospirenone progestogen-only pill | More than 24 hours late (more than 48 hours since the last pill) | 7 days; skip the inactive pills if any of the last 7 active pills were missed |
These are the times in UK sexual health guidance. If you are not sure which pill you have, treat it as the strictest window and ask a doctor or pharmacist.
What should you do if you miss a combined pill?
Take the last pill you missed as soon as you remember, even if it means taking 2 pills in one day, and carry on with the rest of the pack at your usual time. What else you need depends on how many pills you missed and where you are in the pack:
Swipe sideways to compare →
| Situation | What to do | Emergency contraception? |
|---|---|---|
| 1 pill missed, or a new pack started 1 day late | Take it now and carry on; no extra contraception needed | Not usually needed |
| 2 or more missed, in week 1 | Take the last missed pill, carry on, and use condoms for 7 days | Yes, if you had unprotected sex in the break or in week 1 |
| 2 or more missed, in week 2 | Take the last missed pill, carry on, and use condoms for 7 days | Not needed if you took the 7 pills before correctly |
| 2 or more missed, in week 3 | Take the last missed pill, finish the active pills, and start the next pack without a break; use condoms for 7 days | Not needed if you took the 7 pills before correctly |
The break between packs is the riskiest time to miss pills, because missing pills at the start or end of a pack makes the break longer, and a long break can let an egg be released.
Can I take 3 pills in one day if I missed 2 days?
No. Take only the most recent pill you missed now, leave the earlier missed ones in the packet, and take your next pill at the usual time. That means no more than 2 pills in one day.
What happens if I accidentally miss one pill?
With the combined pill, one missed pill, up to 48 hours late, does not usually matter: take it as soon as you remember and you stay protected. With a progestogen-only pill, being outside your window, even by a few hours, means extra contraception and possibly emergency contraception.
What should you do if you miss a progestogen-only pill?
If you are still within your window, take the pill as soon as you remember and you are protected. If you are outside it:
- Take one pill as soon as you remember, even if you missed more than one.
- Take the next pill at your usual time, even if that means 2 pills in one day.
- Use condoms or avoid sex for 48 hours with a traditional pill, or for 7 days with a desogestrel or drospirenone pill.
- With a drospirenone pill, if any of the last 7 active pills were missed, skip the inactive pills and start the next pack.
- Get emergency contraception if you had unprotected sex after the missed pill, before protection was back.
I forgot my progestogen-only pill last night: what now?
Count the hours from your usual time. A desogestrel pill taken the next morning, less than 12 hours late, still protects you. A desogestrel pill 24 hours late is outside the window: take it now, carry on, use condoms for 7 days, and think about emergency contraception if you had sex since you missed it. A traditional pill more than 3 hours late follows the same steps with 48 hours of condoms.
Vomiting, diarrhoea and other reasons a pill may not work
A pill only works if it is absorbed. These situations count as missed pills:
Swipe sideways to compare →
| Situation | What to do |
|---|---|
| Vomiting within 3 hours of a combined pill | Take another pill; if you cannot keep one down, follow the missed pill rules |
| Severe diarrhoea for more than 24 hours on the combined pill | Follow the missed pill rules |
| Vomiting within 2 hours of a traditional progestogen-only pill, or 3 to 4 hours of a desogestrel or drospirenone pill | Take another pill within your window; if you cannot, follow the missed pill rules |
| Severe watery diarrhoea soon after a progestogen-only pill | Take another pill as soon as you can |
| Sickness or diarrhoea that keeps going | Ask about a method that is not swallowed, such as the patch, ring, implant or a coil |
If you have had a stomach bug while travelling, the travellers’ diarrhoea page explains how to manage it.
Do you need emergency contraception after a missed pill?
Only in some situations. With the combined pill, it is usually needed when 2 or more pills were missed in week 1 and you had unprotected sex in the break or in week 1. With a progestogen-only pill, it is needed if you had unprotected sex after a pill outside your window, before protection was back.
If you need it, the emergency contraception page explains the options. Restart your pill straight away after levonorgestrel; after ulipristal acetate, wait 5 days before restarting, using condoms meanwhile.
Can you get pregnant if you miss one pill?
With the combined pill, it is unlikely after a single missed pill if the others were taken correctly. The risk rises with each missed pill, especially around the break. With a progestogen-only pill, the risk starts as soon as you are outside the window.
Missed pills and no bleed in the break
If you missed pills and then have no withdrawal bleed, do a pregnancy test, and repeat it 3 weeks after the last unprotected sex.
What might the doctor recommend after a missed pill?
This is the framework the doctors use, in line with UK sexual health guidance:
Swipe sideways to compare →
| What you have | Likely first step | Suitable for online care? | When in-person care is needed |
|---|---|---|---|
| One combined pill missed, no other problems | Take it and carry on | Yes | Not needed |
| 2 or more combined pills missed in week 1, with unprotected sex | Emergency contraception and 7 days of condoms | Yes | If the copper IUD is the best option |
| A progestogen-only pill outside its window, with unprotected sex | Emergency contraception, then condoms for 48 hours or 7 days | Yes | If the copper IUD is the best option |
| Pills often missed | A method that does not depend on daily pills | Yes | For an implant or a coil |
| Missed pills and no withdrawal bleed | A pregnancy test | Yes | If the test is positive |
| Positive pregnancy test with pain low in the tummy | Urgent assessment, including for ectopic pregnancy | No | Urgently; call 112 for severe pain or fainting |
Not sure whether you are still protected? A doctor can tell you in one consultation.

What you can do yourself
- Take your pill at the same time every day, tied to something you never skip, and set a phone alarm.
- Keep a spare pack in your bag, especially when travelling.
- Keep the leaflet or a photo of the pack, so you know your pill’s window.
- Across time zones, keep roughly the same interval between pills rather than switching straight to local time.
- Use condoms with new partners: no pill protects against sexually transmitted infections.
Prescription treatment
A prescription is never issued without a consultation. After going through what happened, the doctor may prescribe emergency contraception, a new supply of your pill, or a method that is easier to keep to, such as the patch or the ring. Longer-acting methods such as the implant and the coils are fitted in person. If the doctor prescribes, use the prescription at a pharmacy near you.
What does not help
Taking all the missed pills at once. Stopping the pack after a mistake, which leaves you unprotected. Waiting to see whether a period comes before getting emergency contraception.
Special situations
Patch and ring
A patch that came off or a ring that came out has its own rules, explained on the contraceptive patch and vaginal ring pages.
Bleeding after missed pills
Missed pills often cause spotting. The breakthrough bleeding page explains when bleeding needs checking.
While travelling in Europe
Time zones, long flights and holiday stomach bugs are common reasons for missed pills. Keep your pill in your hand luggage, count your window from your usual time at home, and carry the leaflet so a pharmacist can see the ingredients.
Children
Mobi Doctor consultations are for adults aged 18 and over. A child who is unwell needs a paediatrician or a local doctor in person, and emergency signs in a child mean 112.
When a missed pill is handled online, and when you need in-person care
Handled online: working out whether you are protected, emergency contraception pills, how long to use condoms, pregnancy test timing, and switching to a method that is easier to keep to.
In-person care: a copper IUD for emergency contraception, implant and coil fittings, and any pain or bleeding with a positive pregnancy test.
When to get in-person care
Call 112 or go to an emergency department now for:
- sudden, sharp and intense pain in the tummy, with feeling very dizzy or fainting
- a positive pregnancy test with severe pain low in the tummy, especially on one side
Get medical advice the same day for:
- unprotected sex after missed pills, for emergency contraception
- vomiting within 3 hours of an emergency contraceptive pill
- a positive pregnancy test after missed pills
- new pain low in the tummy on one side, or pain in the tip of your shoulder, if you could be pregnant
How Mobi Doctor works
- Book a time that suits you: daily 7am–11pm CEST. You can see a doctor over video, usually within 15 minutes. No subscription, and the exact price is shown before you pay.
- Speak to a licensed doctor about what happened: have your pill packet to hand, and say which pills you missed, how late, and when you last had sex.
- Leave with a plan: what to do, what to take and for how long, and which signs mean you should be seen in person. If the doctor prescribes, use the prescription at a pharmacy near you.

Frequently asked questions about missed pills
What happens if I miss one pill?
With the combined pill, one pill up to 48 hours late does not usually matter: take it when you remember and carry on, and you are still protected. With a progestogen-only pill, being outside your window means condoms for 48 hours or 7 days, and possibly emergency contraception.
How many hours late is a missed pill?
A combined pill is missed when it is more than 24 hours late. A traditional progestogen-only pill is late after 3 hours, a desogestrel pill after 12 hours, and a drospirenone pill after 24 hours.
Is a late pill the same as a missed pill?
Not always. A combined pill is only counted as missed when it is more than 24 hours late, so a pill a few hours late is simply taken when you remember and you stay protected. Progestogen-only pills have much shorter windows: 3 hours for a traditional pill, 12 hours for desogestrel and 24 hours for drospirenone, and once you are outside the window the pill counts as missed, however short the delay.
Can I take 3 pills in one day if I missed 2 days?
No. Take only the most recent missed pill now, leave the earlier ones, and take your next pill at the usual time, so no more than 2 pills in one day. Use condoms for 7 days, and check whether you need emergency contraception.
Do I need the morning-after pill if I missed a pill?
With the combined pill, usually only if you missed 2 or more pills in week 1 and had unprotected sex in the break or in week 1. With a progestogen-only pill, you need it if you had unprotected sex after a pill outside your window, before protection was back.
What should I do if I miss my desogestrel pill by 24 hours?
That is outside the 12-hour window. Take one pill now, take the next at the usual time, use condoms for 7 days, and get emergency contraception if you had unprotected sex since you missed it.
What are the missed pill rules for the mini pill?
Take one pill as soon as you remember, carry on at your usual time, and use condoms for 48 hours with a traditional pill or 7 days with a desogestrel or drospirenone pill. Get emergency contraception if you had unprotected sex before protection was back.
Does vomiting count as a missed pill?
Yes, if it happens soon after the pill: within 3 hours of a combined pill, within 2 hours of a traditional progestogen-only pill, or 3 to 4 hours of a desogestrel or drospirenone pill. Take another pill; if you cannot, follow the missed pill rules.
I missed a pill and had unprotected sex. Can I get pregnant?
It is possible, especially with a progestogen-only pill outside its window or after 2 or more missed combined pills in week 1. Get emergency contraception as soon as you can, and do a pregnancy test 3 weeks after the sex.
How long after a missed pill am I protected again?
After one missed combined pill you were never unprotected, so there is no waiting time. After 2 or more missed combined pills, or any missed progestogen-only pill, protection returns once you have taken the pill correctly for 7 days in a row, or 48 hours for a traditional progestogen-only pill, so use condoms until then. If you had unprotected sex before that, you may still need emergency contraception.
I missed pills and did not have a bleed. Am I pregnant?
Not necessarily, because missed pills themselves can change your bleeding, but do a pregnancy test. If it is negative and you had unprotected sex in the last 3 weeks, repeat it 3 weeks after that sex.
What if I keep missing pills?
If you keep missing pills, a method you do not have to remember every day may suit you better: the patch is changed weekly, the ring monthly, and the implant and coils last for years. A doctor can help you choose.
Can an online doctor help after a missed pill?
Yes. After a missed pill, a doctor can tell you by video whether you are still protected, how long to use condoms, and whether you need emergency contraception, which the doctor may prescribe.
