Hi, I Noticed A Little Unusual Bleeding Recently. I Started

Hi, I noticed a little unusual bleeding recently. I started the Depo-Provera shot a couple months ago and this week I started a light period. I also seem to have a bleeding hemorrhoid so it sucks. Any idea why I'm having a period?

I haven't had a period since I started the shot and you aren't supposed to start bleeding til around 6 months after.
