birth control
"I've been on this form of birth control for about two years. I couldn't be happier with it. In the beginning I would have extremely light periods every couple months. But now I haven't had a period in several months. I believe I had some mood swings for a few weeks in the beginning. I have acne here and there but I don't know if that's from the Nexplanon or not. 
My sister is also on this birth control and she loves it as well. She said she had extreme mood swings in the beginning but then they leveled out as well."
