Working up until due date

Are any mamas out there working up until they are due? I get 6 weeks paid maternity leave, but it doesn’t start until I actually give birth. I have some vacation time, but not a lot. I am wanting to save that time in case baby gets sick, for follow up doctor appointments, etc. I am just concerned that I could go into labor while I am at work! I work an hour away from home and I’m not sure what I would do if my water broke in my office 😅 I have a little over three weeks left until my due date. I don’t even know if I am dilated at all yet.
