birth control
"I've been using this pill for approximately 2.5 years. I have never had any trouble with it, never gotten pregnant. Disclaimer: I DO take it everyday, hardly ever skip, and when I do forget, I double up the next day, so I think I've got myself covered. I did not experience weight gain (but I'm pretty physically active 5'3 120lbs). Cramps, well sometimes but not bad, no problems with acne, no mood swings (unless I'm ON my period, but that's a given). If you're young and seriously unprepared for the risk of having a child, I would recommend making sure your partner STILL uses a condom even if you're on birth control, trust me (3 Years and its worked for, knock on wood)."
