Etonogestrel
"I've had Nexplanon since 11/5/14 and the whole first week I had extreme nausea, then bled for 3 weeks, was okay for about a month and now I'm back to nonstop bleeding, extreme nausea, very anxious, crying all the time, acne, and I'm just overall very unhappy and no longer myself. Having it removed next Monday but I'm not sure I can wait."
