Am I losing my baby?

I'm 5 weeks & 6 day pregnant. Today I felt something slip out & went to check & what I saw was yellowish sort of discharge. I took 3 paracetamol & a couple of diazopan to relax me but I just felt it again and I went to see & this time it looked like blood. Now I have a full on pad on just to be sure what I'm seeing. Am I going to lose my baby?
