Dark red period

Becks

HI Everyone,

I am getting a little worried now. I have had PID before and now I am still experiencing dark red period. I know you can get dark brown period before and after which causes old blood but this is continuously now and I don't know why? I will call the doctor but I just want to make sure everything is okay down there aswell to clear my mind. If someone please help or give any advice what it might be that would be great thanks.
