Need opinions comments, just someone to talk to

My af is due in 3 days.. 8/23, so far I've been having cramps for the past week and a slightly stuffed nose, the last two days I've been kinda feeling a little nauseas but nothing major... have any of you ladies felt like af was coming but indeed we're prego? I have so much white sticky cm, I just feel different. My cramps have been more sharp then before, and I haven't had cramps start so soon before my actual af came.. please comment - also bfn so far
