Nuva Ring Started Yesterday, Got Ny Period and Brown Discharge Today???

I feel like being totally upfront might help my situation a little.....

I started on the Nuva Ring yesterday (thursday) had anal intercourse last night, not vaginal. When I took the Nuva Ring out BEFORE we fooled around, I saw a small amount of brown discharge.
Today, (friday) I went to the bathroom, and noticed brown and blood on the toilet paper. I removed the Nuva Ring, and noticed sticky brown, on the ring. I cannot call a doctor until Monday, and until then I will not be engaging in any sexual activity... but Im curious to see if anyone can help me, before i talk to a doctor monday.

PS: I have been on Nuva Ring in the past, (last year, stopped using it for a long time) and have only been wearing the new ring for 1 day. I am due for my period sometime next week. DId my period come early despite just inserting the NuvaRing?
