What’s going on?

My pregnancy test have been negative… I’m on cycle day 53 and yesterday evening I peed and when I wiped it was light pink. I put a tampon in expecting my period to show. Pulled it out 45 minutes later and there was brown blood.. old blood. And so then I put a pad on so I could see more about what is gonna happen next lol… but since the tampon and old blood last night there’s been nothing else…. Thoughts?
