birth control
"This was my first time on the pill, and I can say that it has been great. I gained a few pounds the first month, but I also started lifting weights and eating a lot more to help build muscle the same time I started taking it, so I can't say definitively that the pill is what made me gain weight (and by gain weight I mean like 5 to 7 pounds--I haven't gained or lost more than 2 or 3 in the past 4 years as a high schooler so that was pretty significant for me). It didn't clear up my acne but it didn't make it any worse, I've had no mood swings, no cramps, no pms symptoms, no bloating, really no side effects at all. The only real change I've experienced by taking this is that it made my period more regular and lighter. I have no complaints"
