birth control
"It's been 2 years, I spotted for almost six weeks straight on the first pack until I had the first period. I gained about 10 lbs but most of it was in my chest. I'm just now getting back to my "normal" weight, which also means my breasts are doing back down. Periods are really light, the last two packs nonexistent. If I'm not careful to take them at around the same time, I will get cramping and sometimes spotting. If the spotting doesn't stop within a few days,  I stop taking the pack for a week and have a period and then start the pack again. Overall I love it, though I have noticed increased night sweats but don't know for sure it's related."
