birth control
"I've had nexplonon for a year and I'm honestly not a fan I have horrible mood swings sex drive is extremely low. Also the weight gain is horrible I went from 137 to 160 in a year and I work out everyday eat healthy nothing will make it go down.  I get a migraine every week. My two friends that were on it gained lots of weight and people who have gone off lost weight in no time. It does prevent pregnancy and I have not got my period but side effects are not worth it"
