I had my last menstrual cycle December 23,2016 I skipped my menstrual cycle for January 2017 but I got one for February 2017 on February 6-10,2017 ... I have been feeling as if I'm pregnant from sore nipples, backaches, headache & just recently (last night) I had been craving Wendy's so I stopped in my way home and ordered a 4for4 and the whole meal was very disgusting. I still tried to force myself to eat it & I took one bite out of my burger and instantly got sick, I had to pull over and regurgitate... not to mention I've been testing and I keep getting a bfn with my hpt .. now I want to know has anyone else experienced anything similar & ended up pregnant?
