I agree with our Community leader that it's not unusual to have all sorts of changes in the breast/breasts when a woman is pregnant.(Hormonal changes)
I think you should stop pushing the painful area as you might cause even more pain.Applying warm compresses might help.Also try to eliminate caffeine (chocolate,colas coffee)
Anyway, it's a good thing that you are having an ultrasound next month to make sure that all is normal.Keep in mind that pain is almost never associated with breast cancer.
Wishing you an easy delivery and a strong healthy baby.
P.S.Please, if you have any additional questions keep it on the same thread. (Use the "post a comment" below the answers you have received ) This helps to have all your information together so we can better help you.
Thank you.
