Enter when you took Plan B or ella and the dates you had sex. See which encounters were before or after the dose, plus birth control restart and testing guidance.
This date-only timeline cannot confirm protection. Multiple doses, interacting medicines, vomiting, weight and ovulation timing may change the advice. Ask a pharmacist or clinician for your situation.
How to use
- Select Plan B/levonorgestrel or ella and enter the dose date.
- Add the sex dates you are concerned about, including sex after taking the pill.
- Optionally enter when you restarted hormonal birth control, then calculate.
Does the morning-after pill protect later sex?
No. Do not assume that a dose protects sex afterward. Use condoms or avoid sex until your regular method is effective. If another unprotected encounter was recent, get advice promptly and explain which emergency pill you already took.
Methodology
Calendar dates are compared with the pill date. CDC guidance permits immediate regular-contraception restart after levonorgestrel; after ella, the usual wait before hormonal contraception is at least 5 days. The output also states the CDC backup guidance. Same-day events and events at the 5-day boundary require exact times. Pregnancy-test dates are 21 days after each encounter, not predictions of ovulation.
