After how many days did you take a bath after giving birth?

Attempted to follow Chinese confinement rules of 30 days before taking a bath, but really couldn't take it! Lasted for 2.5 weeks. Lived on dry shampoo and sponge baths and Betadine fem wash for 'down there'. Really weird though -- after I took that bath (aaaaahhh) I was shivering at night! Prior to that day, I always felt warm even with the AC on. Maybe there is something to that 30-day rule...
