I had a C section 9 weeks ago ...........?

I had a C section 9 weeks ago and have had some problems with the incision.2 weeks ago it finally healed up and my Dr told me it was finally closed. Well today I tripped while carrying my baby so I couldn't catch myself. I landed on my stomach and now the incising hurts like hell and is oozing this pink goop. I have a Dr appt Monday for my pap but I was wondering if I should maybe go to the ER today. I don't really want to take my baby to the ER. Should I wait until Monday or go tonight? What would you do?
