periods-pcos in Gastric Sleeve Surgery Forums Posted April 24, 2014 I was sleeved on 3/27 and have PCOS too. Ever since I started the pre-op diet, I've had just a little bit of bleeding every single day - but not a full on period. My doctor said that the estrogen is flowing like CRAZY after the surgery and your body is just bazerk - and it will stabilize. I've not ever had normal periods - even as a teenager. However, I was able to get pregnant wthout any problems. I've lost 35 pounds so far and I think I felt myself ovulate yesterday. I had a painful cramp down where my right ovary is and doc said that's probably what it was (it's now gone away and my gallbladder is already gone). It's amazing how my body will talk to me! Good luck - hope this helped some.
