Yeah that's low enough to cause you some trouble. Tell your doc. They may not be able to do a whole lot but it depends on your health. Mine was 90/50 for several weeks which is pretty low but they didn't do anything. I started eating sausage amd bacon and drinking coffee, I think it might have helped a little bit. It came back up and stayed up by itself in 3rd trimester.
Could also be an indication of dehydration, make sure you're getting enough fluids!
