I had sex last night and used a condom and im on birth control and he said that the condom broke so he took it off but i didn't realize he wasn't wearing it and when i asked if he finished he said no but there was stuff on the couch. Should i take plan b to be safe? I also take the pill today that makes me get my period and i usually get it the day after. Should i wait and see if i get my period or not or should i just take it to be safe?
