Confused

I just need someone to talk to at the moment because I'm at the point of pure confusion. So my period is two weeks late. Today I experience what I know is spotting. Problem is, it went from light red to pink. Two pregnancy tests say no I'm not pregnant, and I'm waiting on the blood results from my doctor. I'm not getting the usual cramping that would come with my period and the only time I see it is when I wipe. Anybody had experience with this. I've been usually normal for the past year.
