"i got the implant towards the end of october 2014 and it is now beginning of march 2015. i didn&#039;t have a period at all until december. it lasted about two weeks and then i got it again on new years. from then i had it continuously for a month and a half. it wasn&#039;t too heavy but still enough to be annoying. my doctor gave me some birth control pills and gave me a set schedule to regulate the bleeding. i finished taking the pill regimen and now i have to see if the period continues. after getting the implant i lost about 17 lbs and was still losing weight except for i started taking the pills and gaining again. my mood and sex drive were a little off at the beginning but quickly returned back to normal."
