Etonogestrel
"I got the Nexplanon March 17th , an I have not stopped bleeding since, it's now April 27th. My cramps have been the worst they've ever been since my bleeding began. I've had massive migraines, I've had either a yeast infection or a bacterial infection back to back no matter how many times I've gotten them treated they come right back. No I have not gotten pregnant, that is the ONLY positive thing about this birth control , other than that I have had a very negative experience an I know I'm only a little over a month in, but from every other females review I have all the same symptoms an I'm debating on if it's even worth waiting to see if it adjusts or not."
