If this was my bitch I would definatley stay with her now as bitches can have thier pups from day 57. You will probably find she will keep you on tender hooks all day then just settle and sleep!!!!! But its better to be safe than sorry, so take a look at your welping kit and make sure you have EVERYTHING you might need to hand so you don't have to leave your bitch and make sure you have got the vets number, just in case.
If you join champdogs you will be able to get lots more help, good luck with your bitch.
