Missing a birth control pill happens to almost everyone at some point. Whether you fell asleep before your usual time, got distracted, or simply forgot, the most important thing is knowing exactly what to do next. The answer depends on which type of pill you take and how late you are.
First: Know Your Pill Type
There are two main types of contraceptive pill, and the rules differ significantly between them.
Combined pill, contains both oestrogen and progestogen. You typically take it for 21 days followed by a 7-day pill-free break (or 28 days with 7 inactive placebo pills). Common brands include Microgynon, Rigevidon, Yasmin, Cilique, Femodene, and Marvelon.
Progestogen-only pill (mini-pill), contains only progestogen. Taken every day without a break. Much shorter protection window: 3 hours for most brands, or 12 hours for desogestrel-based brands (like Cerazette, Cerelle). Common brands include Norgeston and Noriday.
Missing a Combined Pill
Less than 24 hours late
You are still protected
Take the missed pill as soon as you remember, even if it means taking two pills in one day. Continue the rest of your pack as normal. No backup contraception needed.
24 hours or more late, one missed pill
Take it now and use backup contraception
Take the missed pill immediately, even if it means taking two in one day. Continue your pack as normal. Use condoms for the next 7 days. If there are fewer than 7 pills left in your pack after the missed one, skip the pill-free break and start the next pack straight away.
Two or more missed pills
Take the most recent one and use backup contraception
Take the most recently missed pill immediately, leave any earlier missed pills. Continue your pack. Use condoms for the next 7 days. If there are fewer than 7 pills remaining, skip the pill-free break. If you had unprotected sex in the 7 days before missing pills, consider emergency contraception.
Missing a Progestogen-Only Pill (Mini-Pill)
Within your window (3h most brands / 12h desogestrel)
You are still protected
Take the pill now and continue as normal. No backup contraception needed.
Outside your window
Take it now and use backup contraception
Take the missed pill as soon as you remember. Use condoms for the next 48 hours. If you have had unprotected sex during the at-risk period, consider emergency contraception.
Why the Pill-Free Break Matters
Missing pills near your pill-free break is the highest-risk scenario
The pill-free break is a planned hormone gap of up to 7 days. If you also miss pills immediately before the break ends or after a new pack starts, the total time without active hormones can exceed 7 days, long enough for ovulation to potentially occur in some women. Always be extra careful at the start and end of your pack, and skip the break if you've missed pills near it.
Estroclic's calendar view makes this easy to monitor: you can see at a glance where your break week falls, which pills you've taken, and whether there are any gaps near the break.

Never do the maths yourself
The Estroclic home screen shows your Protection Window card in real time, your reminder time, the exact "must take by" deadline, a SAFE / AT RISK status, and a countdown bar. The window is calculated based on your pill type, so it's always personalised to your situation. Your Pack Summary in the Insights tab shows your adherence rate, total pills taken, and missed pills for the current cycle. You can export a PDF cycle report to share with your doctor or pharmacist if needed.

Consider emergency contraception (such as levonorgestrel, e.g. Levonelle, or ulipristal acetate, e.g. EllaOne) if:
- You missed two or more combined pills and had unprotected sex in the 7 days before missing them
- You missed a mini-pill and had unprotected sex during the at-risk period
- You are uncertain about your protection status
Emergency contraception is most effective the sooner it is taken. It is not a regular method of contraception. Contact your GP, pharmacist, or sexual health clinic as soon as possible.
Preventing Missed Pills in the Future
The most common reasons women miss pills are forgetting during a busy routine, illness, travel, and not having the pack nearby. Strategies that help:
- Set a daily alarm on your phone, don't rely on memory alone
- Set a second backup alarm 30 minutes after the first
- Link pill-taking to a fixed habit (brushing teeth, a nightly cup of tea)
- Keep your pack somewhere you'll see it, not hidden in a drawer
- Use an app like Estroclic that tracks your protection window in real time
