My doctor advised me to start taking my blood pressure at home and today it was 109/64. I think that's a little low, but is that good? I'm not sure if low blood pressure it considered a problem during pregnancy. I'm extra swollen today and have seen a few spots in my vision, which is why I took my blood pressure. I'm only supposed to call my doctor if my bp is abnormal, otherwise she told me to ignore the swelling and spots. What do you think?
