Dear sue2773 - I am afraid I cannot answer this question. This forum is for infertility patients, and my expertise is not in managing third trimester pregnancy and delivery.
I have high levels of IGM and IGG. The higher they are the more likely you are to have clotting episodes, so I wuld think the lower levels might indicate a problem with inability to clot. If that's so, they may suggest a vitamin K therapy to help increase your levels. I sure hope all goes well for you and your baby.
