So my AF is due today and I am terrified to test!! No signs of her yet today other than the cramping I have been having for almost a week now. Also since yesterday I felt like I was coming down with something, have been having diarrhea (sorry TMI) hot flashes (which have been going on a few days as well), gas, and nausea. I really don't know what to think. I'm scared to test because it seems like every month something different happens that convinces me this is my month and then either AF comes or I get a BFN so I just don't wanna be disappointed yet again
