birth control
"I am 20 yrs old when I initially got it inserted  waited a month for unprotected sex with my bf to make sure it's effectiveness, everything was great the first 8-10 months I stopped getting my period and most importantly the implanon was very effective, no weight gain, when I reach about a year/year and a half I started getting acne which I've never experienced before, at the time I didn't realize it was the implanon until I started researching, my period started coming VERY irregular, it lasts months with a 2-3 break, made it very uncomfortable to even want to have sex.  So over all it does prevent you from getting pregnant and its very effective but keep in mind these side effects!I only regret it bc of the mood swings,acne, period duration"
