Had unprotected sex on the fourth day of periods last month. Date: 15th. Also had I-Pill next day( 16th nyt). Did not hav any side effects then. Normally hav a 28 day menstrual cycle. So periods should hav started by 12th of this month. Not yet got periods. Is it due to side effect of pill o due to pregnancy?

Hello.
Welcome to HCM.
This is Dr. Swarnava Dattagupta answering your query.

See, first of all, having unprotected sex on 4th day of menstrual cycle in unlikely to result in a pregnancy. Plus you had taken i-pill which has a failure rate of only 3%.
So chances of pregnancy can be ruled out.
After taking these pills, some experience mild spotting and some don't. And mostly, the next normal period gets delayed by few days. It is common. So don't worry, your period is expected within few days.

Hope this was useful.
Contact me for any further queries.
Regards
