Light bleeding for 3 days?

Vanessa
So Thursday (3-18-17) my doctor checked me and i was 3cm dialated. Immediately after he checked me i started to spot then it incresed to a lot of discharge with pink and brown blood. I called my nurse and she said its normal after a checking that if it increased to go to the hospital. Well it stopped for a little bit. It started again for a little bit Friday (3-19-7) and now today Saturday (3-20-17) but its more thick. Any suggestions on what i should do.
