Contraceptive implant and my period

So I got the implanon inserted in my arm almost a month ago, and I mostly just got it because I thought it would stop my period. I know the pill would be a better option for that reason but the implant was easier for me. So now a month later I just got my period and I’m on my 9th day and still have it, it’s also still quite heavy. I also had never really experienced cramps and it is making them so much worse! Has anyone else with the implant experienced this? Did your period stop completely? Please share your experiences!!
