hi so my boyfriend and i had sex yesterday and today. he kind of pulled out both nights and i'm on the pill but i take it at different times every night (between 11pm and 1am)... we had sex in a hot tub tonight and even though he pulled out the hot tub thing worries me. the last time i missed a pill was a week ago from yesterday. but i've taken them since then... should i get plan b or do you think we are okay?
