birth control
"I got switched to it because with the birth control I was taking my periods were irregular. Both of the months that I was on this I had two full periods, one in week 3 and one in week 4. I had mood swings and I was emotional the whole time I was on it. And the worst part is that I've weighed the same thing for the past 10 years, and after being on this for 2 months I gained 10 pounds and after 2 and a half months of not being on any birth control I still have it. Two months was way too long for me."
