Is one emergency pill enough if we had sex again?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My girlfriend recently took the morning-after pill (the 72-hour pill) to prevent an unwanted pregnancy. However, after that incident, we ended up having intercourse again the next day. Does she need to take another pill?

Please guide

Hi,

Welcome to icliniq.com.

I understand your concerns.

The Unwanted 72 pill (Levonorgestrel) primarily works by delaying ovulation. It is designed to prevent pregnancy following a specific "oops" moment that has already occurred.

The pill she took the previous day does not provide protection for any future sexual encounters. It clears the system relatively quickly and does not act as a preventive measure for sex that occurs on the next day.

If sperm were introduced on the evening of the next day, that represents a new "event." If her body ovulates shortly after the effects of the first pill wear off, she could still be at risk of becoming pregnant.

Medical guidelines generally suggest that if another instance of unprotected intercourse occurs, a new dose of emergency contraception is needed. Here are some important factors to consider:

Taking multiple doses of emergency contraception within a short time frame can significantly disrupt the menstrual cycle, leading to heavier or irregular bleeding and nausea. This can be described as a "hormonal storm" for the body.

These pills are not 100 % effective, especially if ovulation has already taken place.

Since the first pill does not cover subsequent sexual encounters, it is advisable to take another dose within 72 hours of the encounter. This is the standard protocol to minimize the risk of pregnancy.

Expect her next period to be early, late, or heavier than usual. These are normal side effects of the high hormone dosage.

Emergency contraception is intended for emergencies only. If she finds herself needing it frequently, consider discussing more reliable, long-term contraceptive methods (intrauterine device, or an implant) with a healthcare provider.

Regardless of whether she takes the second pill, consider taking a pregnancy test three weeks after the last encounter for peace of mind.

If you have any more questions, feel free to ask. I would be happy to guide you. Please keep your valuable feedback for better patient care.

Thank you so much.
