Driving

I drive about 45 minutes or so to and from work. I was planning to work right until the end which I did with my first pregnancy, although at that time I worked ten minutes from home and my husband would drop me off and pick me up. So far I feel okay, but it’s starting to become difficult to drive that far because I have to pee every ten minutes!! My work is pretty flexible as far as me starting maternity leave, but I haven’t been at my job for a year so I’m not even getting paid leave. When do you think you will stop driving/commuting?
