Keep working?

My boss didnt put me on the schedule anymore after last week. She said I could go in and make my own hours so I dont have to use that much of my fmla before baby is born. Only drawback is that I commute to where I work 1 hr, and Im 39weeks3days and exhausted these days. Wondering whether I should take advantage of the time off or keep working until hes here (I cant afford to take off 12 weeks, so Ill most likely be doing 6-7 I think... what would you do?
