Etonogestrel
"I've had a great experience so far on Nexplannon. While I did have a serious bruising issue for about a week and a half at the incision point, it went away. Absolutely love it as birth control! However, I'm noticing that exercise makes me nauseous. Even biking to class! Also, when I get hungry but aren't home to eat, I get nauseous too. Other than that, no weight gain (I've actually lost weight after gaining 15lbs in 8 mos on pills! That was my reason for switching) no hair loss and only super minor spotting. Pretty much completely satisfied!"
