I need advice!

Hey everyone! So I'm supposed to get AF in 2-4 days (all my apps that track AF couldn't agree on a date that I'll get it) the past week I've thrown up , horribly sore boobs, moody as hell, and down there smells different and my bf says it tastes different. I've gotten nothing but BFN, but I'm so confused with all these symptoms and the negatives! Anyone have this happen?! Please tell me I'm not alone, I've cried for so long after this!!!
