So I am 11 days late for my af now and have had 3 negative tests. I was ovulating around the 11th-12th or so I thought.. I had spotting as well as a tiny bit of ewcm and then roughly a week or two ago I had sensitive nipples, started feeling a bit nauseous, sore back, out of breath easily and had hot flashes and now this past week I've had nothing aside from excessive bloating and pains from it as well as fatigue. Took a test and it was negative so I ended up going to emerge to see if I had something else going on and they took a test too and it was negative and they couldn't see anything wrong, took a test 2 days ago and it was negative as well... I'm not sure what to think.. has this happened to anyone else?
