Help!!

Debating whether or not I should call out of work and see how the rest of this day/night goes... Work up at 4am because I realized I've barely felt him move since Sunday morning. Got him to move a little bit, fell back asleep and then woke up at 7 with a painful contraction. Another one an hour later, then just mild sporatic ones the rest of today. A lot of pelvic pressure to the point its difficult to walk, roll, move, sit, anything... They have me working 7-midnight tonight. And I REALLY don't want something to happen while at work. I've worked every day for 6 days straight, not having much resting time.
