I am 22 years old I was on birthcontrol for about a year and got off in may2012 and had a regular period for 3 months but when September came nothing and now I am about 12 weeks late on my period. I have taken home pregnancy test, pregnancy test from the doctors, and a blood test and they all come back negative. (My dr is even stumped) But never in my life have I been late like this. I do not have tenderness in my boobs but I do feel like I want to puke when I'm hungry (not normal for me) and I did puke randomly once well I went out to eat with my bf but after I felt fine. I feel sleepy all the time have gained 6 lbs in about 2 months and again not normal for me. I have been stressed but even when I was stressed in my past I always got a period. And late yesterday I went to the bathroom and seen brown stuff on my underwear like dry blood and when I whipped it was just a little discoloration and today very faint discoloration on my undies and when I wipe. Im so lost is this my period or does this happen when your pregnate? Or am I even pregnate?
