What to do when you forget a birth control pill — every scenario covered.
Forgot to take your birth control pill? What to do
- Late by 24 hours or less → take the missed pill as soon as you remember, then continue at the usual time
- Missed 1 pill (24-48 hours late) → take the missed pill right away; you may need to take 2 pills in one day
- Missed 2 or more pills (48+ hours late) → take the most recent missed pill right away, use condoms for 7 days, and consider emergency contraception if you had unprotected sex
- Progestin-only pill (mini-pill) → late by more than 3 hours counts as missed; use backup contraception for 2 days
- Follow the catch-up steps correctly and the pregnancy risk stays low: 0.25% after missing 1 pill, 0.83% after 2, 1.6% after more than 2 (Obstetrics & Gynecology) — no pregnancies occurred in the group that followed the correct catch-up instructions

Forgot to take your birth control pill? The correct fix by pill type
Forgot to take the pill? Missing a pill happens more often than most people think. CDC data show that about 31% of women using the pill missed at least one pill in the previous 4 weeks, and research from PMC found that roughly 1 in 2 women of reproductive age has missed at least one pill in a given month.
Missing a pill does not automatically mean pregnancy. What matters is knowing the correct way to respond, which depends on the type of pill you take, how many pills you missed, and when in the pack you missed them.

Forgot the combined pill? What to do
The combined pill is the most widely used type, available in 21-pill and 28-pill packs. How to respond to a missed pill depends on how late you are and how many pills you missed.
Missed 1 pill (late by 48 hours or less)
This is not high risk. Do the following:
- Take the missed pill as soon as you remember (even if that means taking 2 pills in one day)
- Continue taking the remaining pills at the usual time
- No extra protection is needed if you took your pills correctly and on time before this
⚠️ Exception: if the missed pill falls within pills 1-7 of the pack (right after starting a new pack) and you had unprotected sex during that time, consider using emergency contraception as well.
Missed 2 or more pills (late by more than 48 hours)
This carries higher risk. According to the Family Planning Perspectives (1997), 27% of women who missed 2 pills in a row were at risk of pregnancy because they used no extra protection.
What to do:
- Take the most recently missed pill right away (discard any earlier missed pills)
- Continue taking the remaining pills at the usual time
- Use condoms or avoid sex for at least 7 days
- If you had unprotected sex in the past 5 days → consider emergency contraception
| Situation | What to do | Extra protection needed? |
|---|---|---|
| Missed 1 pill (within 48 hrs) | Take the missed pill immediately, continue as normal | Not needed (if previous pills were on time) |
| Missed 2+ pills (more than 48 hrs) | Take the most recent missed pill immediately, discard earlier ones | Use condoms for 7 days + consider emergency contraception |
| Missed within pills 1-7 + had sex | Take the missed pill immediately | Use emergency contraception + condoms for 7 days |
Forgot the mini-pill (progestin-only)? What to do
The progestin-only pill (mini-pill) is more time-sensitive than the combined pill because its hormone wears off faster. According to Cleveland Clinic and NHS:
Standard mini-pill (norethindrone / norgestrel)
- More than 3 hours late from your usual time counts as "missed"
- Take the missed pill as soon as you remember
- Use condoms or avoid sex for 2 days
- If you had unprotected sex in the past 5 days → consider emergency contraception
Drospirenone (DRSP) mini-pill
- More than 24 hours late counts as "missed"
- Take the missed pill as soon as you remember
- Use extra protection for 7 days
| Mini-pill type | Late beyond this = missed | Extra protection needed |
|---|---|---|
| Norethindrone / Norgestrel | More than 3 hours | 2 days |
| Drospirenone (DRSP) | More than 24 hours | 7 days |
Forgot a pill in week 3 of the pack? What to do
Missing a pill during week 3 (pills 15-21) needs special handling:
- Take the missed pill immediately, then continue until you finish all the hormone pills in the pack
- Skip all the placebo (inactive) pills and start a new pack right away, with no break in between
- Use condoms for 7 days
- You may not get a period during this time — that is normal
Forgot a placebo (inactive) pill? Do you need to do anything?
No action is needed. Placebo pills contain no hormones — they exist only to help you remember to take a pill every day. Missing a placebo pill has no effect on contraceptive effectiveness; simply start the next pack on its usual schedule.
Will you get pregnant after missing a pill? What it depends on
The chance of pregnancy after missing a pill depends on 3 main factors:
- How many pills you missed — the more pills missed, the higher the risk
- When in the pack you missed them — missing pills early in the pack (pills 1-7) is riskiest, since it follows the hormone-free interval
- Whether you had unprotected sex — if you did not, the risk is very low
According to research published in Obstetrics & Gynecology:
- Took every pill correctly → 0.09% chance of pregnancy per cycle
- Missed 1 pill → 0.25%
- Missed 2 pills → 0.83%
- Missed more than 2 pills → 1.6%
Importantly: no pregnancies occurred at all in the group that missed pills but followed the correct catch-up instructions.
When do you need emergency contraception?
Not every missed pill requires emergency contraception. Consider using it when:
- You missed 2 or more combined-pill doses in the first week of the pack and had unprotected sex
- You missed a mini-pill and had unprotected sex in the past 5 days
- You started a new pack more than 2 days late and had sex during the hormone-free interval or afterward

Tips to stop forgetting your pill
If you often forget to take your pill, try these methods:
- ⏰ Set a phone alarm for the same time every day
- 🪥 Pair it with a daily habit, such as taking it while brushing your teeth in the morning or before bed
- 📱 Use a pill reminder app — many are free to download
- 💊 Keep the pack somewhere visible, such as by your dressing table or your water glass
- 🔄 Consider a different method if you genuinely forget often — options like the patch, an IUD, or an implant do not require a daily dose
Summary: what to do if you forget your pill
Case — what to do: Missed 1 pill (combined) — take it immediately, continue as normal, no extra protection needed. Missed 2+ pills (combined) — take the most recent one immediately, use condoms for 7 days, consider emergency contraception. Missed a pill in week 3 — continue until the hormone pills are finished, skip the placebo pills, start a new pack immediately. Missed a placebo pill — no action needed, start the next pack as usual. Missed a mini-pill by more than 3 hours — take it immediately, use condoms for 2 days. Missed a DRSP pill by more than 24 hours — take it immediately, use condoms for 7 days.

Frequently Asked Questions
Usually not. If you are less than 48 hours late, take the missed pill as soon as you remember and continue the rest of the pack at your usual time — the pregnancy risk from missing one pill is only around 0.25% per cycle. Emergency contraception becomes worth considering only if the missed pill falls early in the pack (pills 1-7) and you had unprotected sex during that window. Ask a pharmacist if you are unsure.
Risk rises clearly once a combined pill is more than 48 hours late, or a progestin-only pill is more than 3 hours late (24 hours for the drospirenone type) — the hormone level in your blood can drop low enough to allow ovulation. Missing several pills in a row, or missing them early in the pack, raises the risk further.
No, it is not dangerous. Taking two pills in one day to catch up on a missed dose is the standard recommended approach. Some people feel mild nausea or stomach discomfort, which usually passes on its own. If you vomit within 2 hours of taking a pill, take a replacement pill right away and ask a pharmacist if the discomfort does not improve.
Yes, this is common. Missing a pill causes a sudden swing in hormone levels, which can make the womb lining shed a little and cause spotting. It usually stops on its own within a few days once you are back to taking your pills consistently. See a pharmacist or doctor if the bleeding is heavy or lasts more than a week.
The same steps apply as for anyone else: take the missed pill as soon as you remember and use backup protection for the required period (2 days for the standard type, or 7 days for DRSP). The progestin-only pill does not reduce milk supply, so it remains a suitable option while breastfeeding. If you miss pills often, or are unsure what to do, ask a pharmacist or your doctor before choosing emergency contraception, since some types carry extra precautions while breastfeeding.
It is worth considering. If you find yourself missing pills often despite trying to remember, a method that does not require a daily dose — such as the hormonal patch, an IUD, or a contraceptive implant — may fit your lifestyle better and lowers the risk that comes with forgetting. Talk to a pharmacist or doctor to find the method that suits your health and routine.
Ask a pharmacist or doctor about emergency contraception as soon as possible — it works best the sooner it is taken, and its effectiveness drops over time. After that, go back to taking your regular pill at the usual time, and use condoms as well for the backup period recommended for the type of pill you take.
Yes. Because the pill must be absorbed through the stomach, vomiting within 2-3 hours of taking it, or severe diarrhea lasting more than 24 hours, can mean the hormone was not fully absorbed. Take a replacement pill as soon as you feel better, and use backup protection just as you would for a missed pill. Ask a pharmacist if you are unsure whether enough of the dose was absorbed.
