I have no idea...

A couple of weeks ago when my boyfriend and I were visiting my parents we had unprotected sex, I’m on birth control and I took the day after pill, but I’ve been over emotional lately. I literally want to cry almost every night, especially when my boyfriend falls asleep early and I’m wide awake. I also have been really crampy thorough out the day this past week. I’m scared to talk to him about it because he is a single dad and we have both said that we are not ready for kids of our own yet, the whole unprotected sex was heat of the Montana we couldn’t find he condoms in our hotel room. So I don’t know if I’m pregnant or not.
