I breastfeed my son, and I was looking at my boobs for the last couple days and I've notice that my areolas have become very dark and huge. I, also notice that my right boob looks very saggy like a deflated balloon, but it has become way bigger than my left, and my nipple points down and then my right boob not so much saggy, but now my nipple points off in a weird direction. Any comments?
