I Have 3 Healthy Childten.but Have Had A Few Miscarriages

I have 3 healthy childten.but have had a few miscarriages as well not abortions. Im 10 wks now with a healthy pregnancy my iron levels are good as is my blood pressure. My dr said to me if i go to term I will more than likely die on the table. Going so far as to calling me "stupid" for being pregnant. He replaced all my joy with morbid fear. I don't know what to do as he won't give me any medical basis for the statement.
