Please help..! BOOB PROBLEM!! 🙃

Me and my husband been trying to conceive...

Well normally with my period coming in 7 days (if I am not pregnant) I noticed last month before my period came my nipples got pretty sensitive and just a tad itchy and dry, nothing crazy. This month my boobs are itching me so much... specially on the nipples (just the nipples lol) my right nipple in particular... i have darker nipples (tan) and the center of the nipple is pink and there’s like tiny pink stretch mark looking things and I am concerned. Could it be pregnancy or is it something I need to get checked out... genuinely concerned.

Is this normal? ... have you gone through it?
