Etonogestrel
"I got my implant inserted in February 2015. I got my period around the beginning of March and bled every single day for 3 months straight. It finally went away and came back 2 weeks later, staying for another 2 weeks. To sum it up, this implant is not for me. It is almost six months in and I'm still having stomach cramps and bleeding and mood swings and everything else...I'm sick of it now!"
