I had my yearly last month. The Gyno wanted me to have an ultrasound. It was vaginal and abdominal. I found out that I have ovarian cysts. My cycles have been bad. Too long and heavy. She says these are signs of this. So her solution was to put me back on the pill to help with these cysts and my cycles. I am usually IBS-D. I am scared. Has anyone had any real bad IBS problems and what side effects can I expect other than nausea for a while. What about weight gain? Moods?
