"i&#039;ve had nexplanon for 14 months and i don&#039;t think it works with my body. the insertion was painless and i like how i don&#039;t have to worry about taking a daily pill. however, since i started nexplanon, my body has reacted as such: 1) my periods last for about 23 days or more when on my former birth control, they lasted only 3 days 2) my face breaks out during my cycle, which didn&#039;t happen on my former bc 3) i never got cramps during my natural menstrual cycle or on my former birth control, but i get cramps on nexplanon; during certain times i would cramp after orgasming oh, and it lowered my sex drive. 4) on the plus side, my breasts would get bigger and fuller for a few days. all in all, i think i will switch back to my old bc, nuva ring."
