Why do my breasts feel like their bruised and swollen? I started taking reclipsen birth control aug. 1st. My period ended sept. 2nd it lasted about a week and was very heavy. Two days after my period ended, my breasts started to feel like they were bruised around the outside, but middle-nipple area has little to no feeling in it. The other day I was changing and my husband says, "OMG! your boobs are huge!" Could the birth control be causing my breasts to do this? Or what else could it be?
