Period on nexplanon

I've had Nexplanon since November 2016.

I didnt have any bleeding the first month. Then there was a brown discharge constantly for the 2nd through 3rd months and my period was think and brown. It was super inconsistent and all over the place.

I'm on my 4th month now and I'm having more frequent periods and they last more than a week. It goes from one period then basically right into the other. My flow is very thick and clotted since I got the implant, and previously it has been more red and bloody than brown like it had been previously.

There was a time in between month 3 and 4 where it felt like it had finally been normalized and that my body had gotten adjusted to the hormones. No brown discharge, no clotted flow, nothing. I'm worried that this period is never going to end! It went from good to go gorey in the matter of a day.

Has anyone else had similar experiences? What did you do
