birth control
"So I've had the implant in for a year and a half. For the first half a year, I essentially had 1 long period that would have a days break from bleeding here and there. It did not hurt nearly as much as my usual period and it was not as heavy, so it was just more of a nuisance than anything else, and stopped me being able to have sex. After that, my period came for a few weeks at a time and would start randomly. Half a year of that and now my periods have stopped completely. I've had no other side affects, aside from maybe being a bit more moody and having more mood swings. It's been half a year of no period and I am loving it. And it was free as I live in the UK and am under 25!"
