I'm 11 dpo, my breasts have been really sore for about 5 days, and for the past 2 days I've had this nasty metallic taste in my mouth that I can't get rid of. I remember experiencing something similar early on in my 1st pregnancy, but I don't recall it happening before the expected arrival of AF (she's due in 2 days). I tested today and got a BFN. Too early maybe? Anyone else experienced a metallic taste early in pregnancy?
