On sunday i lost my virginity. i was supposed to begin my period on monday and am now 3 days late. i have been on the birth control pill for 3 months?

Do a test: You're not likely pregnant unless you have missed pills. Check on a first morning urine just to be sure.

Doubt Pregnancy...: If you are taking your birth control pills correctly without missing pills, its very unlikely that you are pregnant from 1 episode of intercourse. Also, intercourse Sunday, is unlikely to delay your period on Monday. Do a home pregnancy test if you want to know for sure. They are available without a prescription at the pharmacy. Some women stop having periods while on the pill. Best wishes!

Period: It is unlikely that you're pregnant but please do a home pregnancy test
