birth control
"I had the implanon about 7 years ago and had it taken out after only a year (not the 3 its allowed).  This was a horrible experience for me. I didn't have a period he entire time, I gained almost 50 lbs, had the worst mood swings, I could feel myself becoming angry/crazy even though often times it was not that serious. Everything made me mad, or made me cry-- just horrible. after having it removed, it took almost 2 and a half years to start my period again and another 2 for it to become regular! when I did first get it, I had a period every 4-5 months. Now that it is a bit regular, I still can not seem to get pregnant. worst decision I ever made was getting the implanon. NEVER AGAIN, nor do I recommend to anyone"
