hi its the plan b it can do this your find its put your period back a few days. good luck
took plan b day after unprotected sex due to 1 missed pill period hasn't come yet and was supposed to start 2 days ago? . i may have missed my birth control pill but i don't know if i swallowed it or if it fell down the drain. i then had unprotected sex three days later but he didn't "finish" and i had taken my birth control pill every day since the day i was unsure if i swallowed it. i took plan b the next morning because i was afraid and now haven't started my period as i was supposed to two days ago. i am worried but may be over reacting. could i be pregnant?
