This article from MedHelp.org and the I'm Expecting app has advice on postpartum bleeding (also known as lochia) and other changes you can expect after the delivery. Look for it in Week 39 of the app, too!

I bled for 6 weeks after my first. Lots of big clots and heavy bleeding for about the first week, and then normal period flow for the rest.
Idk about discharge, but with my first I had my post pardom period for 4 weeks, very heavy + clots. With my second it was for three weeks with blood cloths only the first 4 days.
