C.D.
I had the same situation and found that dehyradation was my issue. Even though I thought I was inputting a lot of fluids I wasn't. I would increase my water intake when these attacks start and see if that doesn't help. I was in the hospital for an unrelated pregnancy issue and started into labor, the first thing they did was to have me drink a large quantity of water..bingo my contractions stopped. 2nd... because of your pregnancy you are protected from being let go, that is the law so I wouldn't worry about your job. Do the best you can at work to the best of your ability and things should be fine. They are just trying to scare you...after you have the baby I would certainly look for another place to work. Take care and Good Luck
