Anyone else working until their due date/csection date/or whenever the hell they go into labor? Lol

I'm almost 34 weeks pregnant and I'm hoping to work until the day of my scheduled cesarean. This is my 4th baby but the 1st time I've worked full time this far along. I work 7 nights a week as a janitorial cleaner, I clean 7 different buildings/businesses. Obviously it's a fairly physically active job😆 Every single day is getting more and more difficult and I've been having some INTENSE painful contractions this past week. Between work and having a 6 yo, 4yo and 1yo, I am ...struggling to keep up and find myself slowing down.

How are all you working mammas managing and coping with the pain and discomfort? Have any of you went into preterm labor due to working active jobs late into pregnancy? My doctor has said to use my own discretion when it comes to work and how my body handles it.
