Etonogestrel
"I recently got the Nexplanon last month and its ok, I've been spotting for the last 2 weeks & now I have severe stomach pains.....I'm still going to give it a shot at east six month, It has caused me to not have an appetite at all not sure if that's normal but since I'm only one month in I'll still consider this for of birth control. It's the stomach pains that are driving me crazy."
