My boyfriend and I don't use condoms but I am on BC. I was supposed to start my period 2 days ago, hasn't come yet. I am having some cramping as if I'm on my period, and I keep feeling wetness as if I'm bleeding but I go to the bathroom and there's nothing, but my undies are a little moist.. I'm usually never late with my period. Can't remember the last time I was. I took a pregnancy test, but it was negative.. am I just over reacting??? Could I be pregnant..?? Or is my period gonna come?
