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

I used the pull-up pants for the first few days because my bleeding was a lot. Afterwards, I used the kotex wings overnight kind. Change every 3-4 hours. Don't use the same one for too long. My bleeding actually lasts for 5-6weeks. I didn't use the maternity pads given by the hospital because I hate using non wings type haha
