I am 20 and have had the nexplanon birth control implant for about a year now. For the first six months, I was on my period almost everyday but about one week a month before my period normalized to closer to one week a month. However, I have been experiencing excessive brown discharge after my period. I know brown discharge is normal, but it’s gotten excessive to the point I’ve continued to wear tampons after my period for around three days. 

Has anyone else experienced this before? Is there any steps I can take to control it ?
