Etonogestrel
"I'm on the second year of having Nexplanon. At first, I loved having it because I didn't have to remember to take the pill every day and my periods stopped all together. Then the 2nd year I started getting random spotting and now I have been having my period for 3 months on and off, weeks at a time. I thought it would go away, but it continuously happens, so I'm getting it taken out. Its a highly effective birth control especially since I get my period every week now. I haven't experienced any weight gain or mood swings at all though!"
