Low Bp during pregnancy is usually a BP of less than 90/60. It’s fairly common and can come from dehydration or even anemia. Drink plenty of water and let your OB know if you’ve been more tired than usual. They can do labs and catch any issues before they get problematic.
I think that it means pretty much the same thing as it does when you’re not pregnant. Your BP is just low and you need to drink lots of water and try to stay off your feet.
