Clotting factor and multiple miscarriages

I just had my 2nd m/c (blighted ovums) in a row and my dr did some bloodwork and said that I may have a clotting factor.  My antithrombin antigen came back at 147, protein c antigen was 145 and homocysteine was slightly low at 4.6.  They have referred me to a hemotologist.  I'm scheduled to go early next month to have more testing done but wanted to know a little more about clotting factors during pregnancy and what it could mean when trying to have more children.  My ob said that a lot of times they will just give you baby asprin during pregnancy.  Could you give me a little more insight on the subject? For instance, why it could possibly cause a m/c, what it could do to your baby if you do get pregnant and stay pregnant and are there any risks?  Thank you for your time.

The levels you are providing are normal. If anything, low levels of antithrombin III and protein C are associated with miscarriages. If anything, a high homocysteine, not a normal value, is concerning. Some infertility specialists believe that abnormalities in some of the proteins that control the rate at which our blood clots can lead to miscarriages. This is a controversial area. Baby aspirin is sometimes used; blood thinning medicines are sometimes used, but rare, and only if there is a clear abnormality. In addition to a hematologist, I would recommend seeing a reproductive endocrinologist -a reproductive endocrinologist would be able to put all of this into perspective.
