birth control
"I was originally in love with this prescription birth control.  I had terrible periods and ovarian cysts. My doctor suggested I have a pill that allows my period to only occur every 3 months, which I loved. It was until recently that I noticed that over the last 6 months, I've gained 20 lbs!!! Going into spring 20 lbs heavier is crazy. I also experienced abdominal pain and menstration pain. I love the space between periods and but I don't love the weight. I will be switching back."
