Is it very painful when pee right after delivery? What about if I need to poop? I will be going for natural delivery.

Yes, it will be a bit sting feeling during pee as the wound is fresh. You can spray some cold water at your vaginal area while peeing as it will ease the pain. Also wash with antiseptic solution after finish peeing and wipe the wound area to keep it dry. My gynae prescribed me stool softener which helped me a lot in relieving the pain during poop. You can request hospital to prescribe for you.
