Hi dr. i had my first intercourse last january 1 at 2am with my boyfriend. i am worried if there is a chance of pregnancy? i also bought 1 box of birth control pills wondering if i should take it since there is no morning after pill in ph.

The ability to prevent pregnancy after sex depends on how many days have passed, and what IUD's or pills are available.
