nervous new time gm to first and last litter looking for support and answers

Hi my cat joy is about to have her first litter today is her due date and im ready but one question what are the odds of her giving birth on her due date and how far past their due date can they stay pregnant without worrying? Also just a bit of convo would be nice while I wait lol.

What is convo?

Cats manage well a little too long pregnancy, unlike humans.

but manage badly a too short pregnancy, also unlike humans.

I will paste in some links in a minute.  You can also look on some youtube films..

Good luck!
