Nexplanon removal....

So, I got my nexplanon removed in the beginning of December of 2018, on my period date in december still, I had my period for a whopping 2.5 days, which is very unusual for me. January I have yet to get it. I've already tested twice, and on both accounts its been negative. I'm seeing my Ob after valentine's day, so I'll be bringing it up then, but I'm paranoid and just wanted reassurance that I'm not the only one this has happened to.
