Etonogestrel
"Absolute nightmare. I've have Nexplanon in my arm for 9 months and I've never experienced a more uncomfortable birth control in my life. I've never had acne in my life, now I break out all the time. Mood swings left and right that have led to full on breakdowns. I'm always tired, can't get out of bed some days. Get used to getting your period twice a month. Currently I'm on a period that has lasted over 3 weeks straight and I'm not talking spotting- it's a full on blood bath with visible clotting. I'm losing a lot of blood and it's completely ruined my sex life. I wouldn't recommend this to my worst enemy."
