Okay so Ive been having some cramping on an off since about the 10th of september, period is due on the 24th.. Have been trying to get pregnant and wondering if my boobs hurting is a symptom.. it always seems to hurt the most when i have a bra on.. its starts off tingly then really hurts so if i am home the bra comes off...also my nipple has a darker ring around it now could these be signs or being pregnant or just that my period is comming?????
