Etonogestrel
"My experience is absolutely terrible with this. I had it out in September 2014. I gained 20 lbs in the first month and another 10 soon after. Now I'm the biggest I've ever been and that's not even the worst part. I've had mood swing, I've been prescribed antidepressants, and most recently I had a period that lasted 5 months straight. I had to double up with pills for it to stop. I get irritable for no reason, I'll go through stints of just wanting to do nothing but lay around all day... I've tried diet changes and working out but the weight just sticks."
