"i have been on depo for 3.5 years now and the first entire year i had spotting almost everyday. after that i would only get my period about a week after i would get a new shot which last at least a full week but are very light. i love this birth control because i don&#039;t have to remember to take a pill every day. i didn&#039;t experience weight gain, i actually lost weight after taking the shot but i did experience some acne which i am not sure is because of the depo or just minor adult acne. i definitely recommend this method for birth control!"
