TMI bloody show???

I'm 38 weeks today. I lost my mucus plug Sunday, or at least part of it, today when I wipe I've been getting pink/yellowish discharge I looked it up and was pretty sure it was the rest of my plug. Then I went to the bathroom tonight and this is in the toilet.... is this normal? I'm having mild contractions in my back not regular enough to time.. baby boy is active as usual.. I have an appt with my dr in the morning but is this hospital time or will the appt tomorrow be sufficient?
