Normally my cycle is 32 days. Last month I was late and went 37 days and had a chemical pregnancy. Now, this month I am at 34 days, no AF and my breast are really tender and BIG (usually they get big but never hurt before AF). I am tired but I've had some stomach bug the past three days (not the throw up kind unfortunately but the other kind) so it could be related to that. i took two tests (one last night and one this morning) and both were BFN's. DH and I defintely BD'd all last month as much as possible and during the time i would be o'ing but since the home tests say BFN i don't know what to think. any thoughts?
