Implanon irregular bleeding

Lauren • 19 👑 in love 💖 budding lawyer, athlete and author 💎
I've been on the implant for about 3 and a half years. I use to never get a period on it, but now I get it monthly. But TWICE a month. It's horrible. It hurts and it's heavy. 
I've been told that the injection works well with this contraception to help stop periods completely. Any advice?
