Bloody breast leakage?

I haven't had my baby yet, I'll be 36 weeks on Monday but I leak sometimes and I noticed a small about of red in with the clear fluid today. I'll see my doctor on Monday, so I'll talk to her then but I was wondering if anyone could help ease my paranoia over the weekend. Anyone else have this? What was it?
