birth control
"I've had problems with birth control pills and in my 30s I tried a Paragard IUD and loved it. Two years ago I tried Mirena because my OB-GYN didn't have Paragard in stock.  I started to gain weight almost immediately and my mood swings from anxiety to depression.  Everyone said that the hormone dose is too low to cause problems and to give my body time to adjust. Recently my doctor removed the Mirena and noted that I used to have low blood pressure, but now it's high, and I've gained over 10 lbs. (same problems I had on birth control pills). I've always had light periods so Mirena provided little benefit and miserable side effects."
