"i&#039;ve been on nexplanon for about 3-4 months now. after about two weeks i started bleeding pretty much non-stop for about a month. i&#039;ve never had regular periods and they always been light or moderate with only minimal cramping. the month long bleeding i had was definitely light, but steady and a nuisance. however, now i hardly bleed at all. i said i don&#039;t have any periods but occasionally i&#039;ll have a couple days of light bleeding. i haven&#039;t gotten pregnant, and have had no weight gain. i&#039;m sorry to hear others experience has been less satisfactory but i would definitely recommend nexplannon. i love that i don&#039;t have to worry about getting pregnant or taking a pill regularly. if it matters, i&#039;m 19."
