birth control
"I am 23 and took ortho tri cyclen lo (OTCL) for about 5 or 6 years. I started taking it to regulate my cycle, for lighter periods, less cramping and all the other positives the pill boasts (and got it!). I am a pretty emotional gal and this seemed to somewhat help. At worst I would say it had no effect on my mood swings but at least it did not make them worse.  over the time I took the pill i gained weight and my boobs grew a cup and 1/2, but i would not blame the weight gain on the pill. OTCL even has cute little cases that you can get from the website for free which i liked and used. I would have stayed on OTCL if I was better about taking it on time and if it were not so expensive ($50 retail, $10-30 w/ insurance)"
