On Friday the 27th of April I had unprotected sex while on my period he came inside of me and I went and got plan b maybe a hour after it had happened. Then my period stopped suddenly the next morning? I then on Sunday started my next birth control pack (I've been taking them for around 1 year now) usually on time but Thursday March 5th I was a hour late taking them. We don't use condoms put he pulls out and I use my birth control. I feel like I have to pee a lot but I don't if that's me just freaking myself out and its usually clear pee? chances of me being pregnant please help!
