Hi i'm 22 years old and want a family like crazy. I was diagnosed with endometriosis 2 years ago. About 2 weeks ago i started LIGHTLY spotting for a few days normally when this happens i start my period  shortly after. But still nothing.... This never happens. I am having cramps like i'm going to start... still nothing. My nipples have been extremely tender, to the point where i wont even let my boyfriend touch me there. I've been crazy tired, and had slight headaches. Took a pregnancy test a week ago and it was negative. Is there a possibilty that i can still be pregnant. I really hope so but i dont want to get my hopes up too much i want this more than anything.
