Had unprotected sex a week and a half ago, took plan b 60 hours after. i am supposed to get my period in 2 weeks, but i had light bleeding which got heavier throughout the day. could i be pregnant? or is something else going on?

Hormonal imbalance: Plan B is known to upset the hormonal balance may induce withdrawal bleeding. Do a home pregnancy test 3 weeks after the episode of sex, if the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. Wish you good health! If you do not wish to be pregnant, use contraception all the time, every time.
