Brown discharge? Or blood

Maddie

I’ve just recently had the rod put into my arm (around the 14th of august) and 2 weeks into it I started bleeding but it wasn’t the usual blood it was brown and I haven’t stopped bleeding since then. it is now the 19th of October and I’m starting to get worried. I’ve also had moments where it’s been stringy and almost like a clot I’m worried this might be a sign of pregnancy? Help?😭
