Etonogestrel
"I've had Nexplanon for 7 months and have been bleeding almost every day for 6 of those months. The bleeding is light, but enough to wear a tampon so it's consistently annoying. On the plus side, once your body gets used to Nexplanon, you forget it's in your arm and I'm also not pregnant, which at the end of the day is its job. I have 3 friends who tried Nexplanon and it worked for 2 of them (they're both on their second ones). Before trying it, be aware that some insurances will not pay for you to get it removed if you want it out before the 3 years is up, so make sure you check with them in case it doesn't work. I do think it was worth the try and would be willing to try it again in the future, but it definitely is still quite flawed."
