birth control
"I was on this birth control for a month and a half. I experienced terrible bloating. I've been thin my whole life, always very active and able to eat whatever I wanted. With this pill, I constantly felt tired and had to monitor what I ate so I didn't gain weight (I gained about 5 pounds, still working out although not as intense as before due to being tired, BUT I was eating less!) Also, this pill affected my mood a lot- it was a subtle change, but then a month and a half later I realized I never had the energy to do anything. I was sad quite often. My acne didn't improve at all, if anything it made it worse. Breast were tender. But, no decrease in sex drive and did prevent pregnancy."
