So my bf and I were churning butter and he came and didn't realize until after that the condom had broken (not a question of whether or not he lied and said he 'didn't realize'- I trust this guy with my life). So right away I peed and took care of things down there and then he took me to the store and bought plan B for me. I wasn't in my fertile window and nowhere near it, plus I took plan B within two hours of the incident. Could I still be pregnant?
