I'm 4 days before AF, about 9 DPO. It definitely could be my brain telling my body what to feel because I want it so bad, but I'm experiencing a few symptoms that are abnormal for pms for me. Sore nipples, dizzy, nausea in morning but no vomit. I tested this morning with a clear blue (because it's what I had on hand) but negative. I know they are only 50% at this point.. am I crazy for thinking of grabbing a first response? Should I just wait for AF. Impatient as F.
