I am 11 days post op after lipo and bbl. Immediately after surgery the results were amazing. But at around Day 7 my butt started to shrink. Seems like each morning it's shrunk more and more. I knew that it would get smaller after swelling and after healing but it's the same size it was before surgery just a little rounder. Why would this happen? I do have hypothyroidism. Could that be a reason why the fat didn't take? I'm so disappointed I'm literally in tears.
