You could end up sitting in a trial that could last past your due date. I could see if it was earlier in pregnancy but a week before you're due... They would have to find a replacement if it was still going when you went into labor so why not just get someone else from the get go.
I asked the receptionist/nurse at my drs office and she said pregnancy wasn't a medical condition, that I still had to go. smh I should've just asked my Dr directly..
