Help please

I am currently 23 weeks pregnant and I had a Pap smear today. Just now I noticed some brown blood on the toilet paper. Is this where I had maybe bled from the scrapping of the Pap or should I be worried? I had my anatomy scan done today and everything was healthy and normal so I'm thinking it's just old blood from my Pap. Any thoughts or opinions?? Has this happened to you after a pap before??
