I have PCOS and take metformin to regulate cycles. For the past few months I’ve been having random sharp pains all over my abdomen. My OB says labs are all fine and my ultrasound shows healthy looking uterus and ovaries with some cysts. I go to see a digestive disease doctor next week for other symptoms I’ve been having with the stomach pains but in the mess of it all I’m now over 25 days late for starting my cycle. Many negative pregnancy tests and my doctor says it’s “normal” to miss up to 2 periods a year but I have never missed one since starting metformin 2 years ago. Has this happened to anyone else?
