5 week update

Hello VSG friends.  I have lost 44 lbs since I started this whole process.  I havent had the famous 3-5 week stall yet.  I had a "slow down" but not a complete stall.  So I am ready when it happens!!!!!  I've educated myself thoroughly.  One thing that happened today that I was totally not expecting,.....I started my period......I havent had a period (without help from meds) in years and years.  I got off my BC before surgery and don't plan to get back on them until after I hit goal....maybe not even then....  I've read that people have early or late periods due to the estrogen being released from the cells.  But I had no idea this would happen.  I have PCOS and I also have pituitary tumor that causes me to have a high prolactin level.  I hought this was really strange.   Anyone else have simular situations?
