I haven't had my AF yet, she was supposed to be due on the 1st of February. I have taken a few pregnancy test and it came out negative. I'm never late on my period. My first day of my last menstrual period was Dec.31, 2018. Lately, I've been feeling tired, nauseous, and constantly going to the bathroom. I have slight headaches here and there but nothing to severe. I had an ectopic pregnancy in early 2018, and the doctors told me I'm pretty much cleared. I'm just wondering if anyone with the same problem as me knows what's going on.
