I worked up until 4 weeks before my son was born. I was on preload though, I loaded four cars, not easy but I bet it was alot easier than it would be as a driver. I cant imagine doing what Im doing 8 months pregnant. My friend who is also a driver worked up until the last month also. I dont know how she did it. I for one, cant reach the pedals in a P1000 without the seat ALL the way forward. There is no way I could have scooted that seat all the way forward 8 months along!
