2 periods on Nexplanon

sa

I JUST had my period the 25th-29th of July. Now I started one again today (aug. 11). No signs or symptoms of it & I was fine yesterday.

Ive been on nexplanon for a year and I have NEVER had a problem. If this is the side effect everyone keeps talking about then im gonna be one pissed off girl. I like this birth control. Has this happened to anyone else?
