I think I'm going crazy, so my periods have been every month since I've had my daughter, well I went to the beach last week when I was suppose to start and I spotted (me and my boyfriend haven't had sex since my last period so being pregnant never crossed my mind) well while we were at the beach we had sex and now that I'm home I'm cramping but no period. I wouldn't mind being pregnant again (he wants me to be) but I can't remember how it felt at the early stage of pregnancy (I know it's way to early to even test anyways) I just think I'm going crazy! Lol
