So I was suppose to get AF last month never came. Took 5 AHTs only one came back with a little line barely to even see, then I went to the doctors did a blood and pee test and they came back negative! Please can someone help me figure out what's going on with me I still haven't had AF yet. I do want to be pregnant but idk if I am or not. I am also 21 DPO and not AF yet. My periods have been regularly since I got off birth control a year a go.
