I had WLS 9 months ago and have so far lost 45kg (currently 69kg, 140ish Ibs) and my boobs have always been slightly uneven but it’s always been the same about a 1/2 cup different. Out of nowhere over night I wake up and one breast is nearly 2 cups bigger than the other! My weightloss has slowed and steadied so I’m not sure if it is that. They are a little tender but not by much. I also had the IUD put in in march but there was no change then. Is this normal?
