"i&#039;m 19 years old and i have only been on the shot for 3 months and some change now. i like the shot. i had regular periods before but they were really heavy and painful. i tried the pills once and took all of them. a couple of times i forgot to take them on time but took two the next day but the shot works better for me. the only negative thing i have to say is it does mess with my moods, like i&#039;ll get sad out of no where and start tripping and the weight gain i don&#039;t mind because i&#039;m already a size 3, i want to gain some weight. during the first month i spotted the whole time. not a regular period just brown spotting. but it&#039;s gone away now and like i said i&#039;ve only been on it for 3 months and some change now so overall for me, i like."
