"depo-provera worked very well. in fact i really loved it. i only gained about 3 pounds (i do work out 4/5 times a week). had my period 3 times a year and it was so easy just one shot every three months. the only downside was i got a bunch of acne and a bit of hair loss. each month around my period i still had the cravings but never got my period! now that i am off my acne cleared up a bit. i highly recommend this birth control! very effective!"
