I got my period pretty late, about 4 days late and the first day I got it was really heavy all of a sudden that same night barely any blood whatsoever. Iam on my third day now, and really no blood it feels like I have my period but theres no blood. I am on the pill as well and have been for a year and my period has been pretty normal with everything. Every morning I wake up feeling sick, I dont throw up but I feel like Im going to. My nipples and breasts seem to have gotten pretty big as well. Could it possibly be pregnancy? Even though I am on the pill? thanx for your help!
