"i started it because of bad periods. i liked it the first month because of no period. after about 2 months i went to the doctor and i had gained 40 pounds. the doctor told me it was my hormones getting leveled out. so i did another shot. within 1 and 1/2 months i gained another 30. i had not changed my diet or anything. so i had gained over 60 pounds. i stopped the shot. it gas been 6 months since i have been off the shot and i have still not got a period and i am still trying to lose the weight.
