For the past week and a half I've been having non stop nausea. 2 days ago I started having cramps that feel like I am about to start my period, but these are different than my normal AF cramps. I'm super tired and feel lightheaded. Anyone ever have pregnancy symptoms this early? I did a HPT a couple days ago and got a BFN and I'm scared to test again I don't want to face the disappointment :(
