Etonogestrel
"I've been on the nexplanon since May 2014.  At first it was great, I got a period like every 3 months, no symptoms hardly at all. This past year though has been hell. I've been having non stop bleeding. I will bleed for 2 weeks straight then it will stop and come back again the following week. Headaches every day, frequent yeast infections, no sex drive at all. Not to mention I've gained like 20lbs. I still have a year left but as soon as I can I'm going to make an appt. To get it out. I can't take it any longer. Only good thing I have to say about it is that It's really good on preventing pregnancy and no worries for 3 years. Other than that I wouldn't recommend it."
