###Human: Being a PCOS patient can I take I-pill effective after sexual intercourse? ###Assistant: Hello. Since you have a longer than usual cycle as expected of PCOS, less likely that you are fertile on the day you had sex. It would be an even added protection that you took the I-pill. The I-pill will work whether you have PCOS or not. Comparing to a non-PCOS patient, you have lower chance of getting pregnant after taking the I-pill. If you took the first pill within 24 hours after sex, it is said to be 95 % effective.
