How many maternity pad or kotex overnight panties do you all change after delivery in a single day?

Honestly can't remember how many times I change throughout the day. It's a heavy heavy bleeding for me. I use pureen maternity pads with disposable panties. Also cooling maternity pads helped me too. I had vaginal delivery and needs to be stitched. The cooling pad helps relieve the soreness. My bleeding completely stop about 7 weeks after giving birth.
