TTC, AF is late. Test was take 4 days before missed, it was negative. Another Saturday morning it was a negative. I'm now 4 days late on AF and I'm a little confused as to what could be going on. I have symptoms of both pregnancy & AF. Throughout my years I've never had cramps or back ache along with sore breast/nipples. But since Friday I have been in pain. There is no CF absolutely nothing there except all these symptoms not to mention extremly fatigue & emotional. Any advice?!? I don't want to take another test for it to be negative.
