The tummy won't go down so quickly. I used a binder, which supports the belly so that it doesn't press down on the wound. So I didn't feel any pain. But must also let it air, otherwise when u sweat, the wound gets wet, can become infected.
When getting out of bed, have to turn sideways and use your arms to push yourself out of bed. Otherwise, wound may open.
As for massage, I only did mine after 6 weeks but according to the massage lady, after 14 days can do already cos they won't exert force on that area, just lightly massage to make sure your womb shrinks back up.
Jiayou! The beginning is the toughest.
