OK so I really need some advice or I'll take pregnancy tests till I get my period... Lol.. So ever since February my AF has either been between a 22 day cycle or 37 day cycle.. Me and my fiancee have been trying since October 2014. Each month I go 5 days past the day I started the month before.. (does that make sense) 😕. And in may no period at all and still no.. All the signs are there.. Sore boob's and nipples.. Cramps... A lil back ache and nauseous. I took a test yesterday morning and BFN.. What should I do???
