I started getting the depo shot when I was 14 all the way up until I was 19. I loved it, I never had any periods and I didnt even gain weight. I am 23 now and have been off the shot for 4 years now I have gained weight since Ive been off of it and my hair falls out so much now! IM not going bald or anything but i do loose alot of hair. I have really bad cramps during my period now when i never use to. Sometimes i bleed on and off for about a month I have been trying to get pregnant now for about 3 years unsuccessfully. I am so scared I will not be able to have a baby. My sister was on the shot for about 5 years also and she hasnt got pregnant yet either! I would recommend for women to try other methods of birth control!
