I am just moving into my 32nd week of a so far healthy and easy pregnancy, my first. I really didn't have any sickness and have had a blast as my tummy is still pretty small and my body is coping well. However, a few weeks ago I mentioned to my OB that I am O neg and he immediately insisted I have the Rhogam shot and all that jazz, only to discover I already have antibodies present. GRRR! He sooo should have known my blood type as I had given them about eighteen vials of blood before this but anyway that's neither here nor there. He insisted as long as the levels stayed at 1-4 everything was jolly. Of course that didn't happen, they have risen and now I have to have NSTs twice a week. My question is, what are they looking for to happen during these NSTs and would any of it be true cause for concern? What would they do in the event something was going wrong?
