Etonogestrel
"I have been on Nexplanon for 3 years & 7 months. When it comes to preventing pregnancy it works like a charm. But the side effects are so damn hard to take. First round I had my period for a year. It was panty liner light but still irritating. I gained weight & was occasionally angry. My second round, well my period hasn't stopped since I got it & its tampon heavy. My mood swings are also off the walls. It's straining my relationship, badly. Thankfully my SO is understanding that it's just the hormones & not me. But he's been arguing with me to get it removed in hopes it'll make us happier. Horrifying panic attacks, bad depression, raging anger. Sometimes it swells & itches where it's been placed. I'm making an appointment to get it removed asap"
