"i&#039;ve been on birth control for about three years. i had the depo shot for 9 months then i switched to the implanon and have had it for 2 years. i didn&#039;t have a period when i was on depo or when the implanon was inserted. the weirdest thing happened i started my period last week and it will stop for a couple days and start up again just wondering if it&#039;s normal for it to happen. since i&#039;ve been on it for so long i didn&#039;t think i would get my period until i had it taken out."
