Nexplanon
"I got the Nexplanon because I struggle with Endometriosis. Since my doctor didn't want to do surgery and I've had bad reactions on other estrogen-based hormonal bc, she suggested I try the Nexplanon implant. At first, I thought it was fine. I felt kind of odd but I thought it was fine. 

By the end of the year on Nexplanon, I had gained 30 pounds, was having depressive episodes, almost fainted a few times among other things. While my period pain was better (since I rarely had periods at all), the emotional symptoms were much worse. Some of this might not be Nexplanon or maybe Nexplanon made certain conditions worse. It's impossible to say for sure but this was my experience."
