Etonogestrel
"I at first thought this would be a good "3 year plan" however I have had my period now for 5 months, headaches, 0 sex drive, and weight gain. Doctor wanted me to wait a couple more months to see if it stops but my energy level has dropped significantly and is getting in the way with being able to please my boyfriend. I can't say that wasn't effective because I'm not pregnant. I know several other girls that have no trouble with this birth control form. However I'm thankful I get it removed in a week."
