How do I know that Hughes syndrome is causing me to miscarry?

I have had 7 miscarriages and I am about to turn 32. I had my first with my ex when I was only 19 and my last about 2 weeks ago with my husband of 5 yrs. I have seen several drs and been tested for several things. It seems as though drs won't test for anything unless you tell them to. I asked my dr about Hughes syndrome or sticky blood disorder. He said when I go back after the first of the year he will test for it. A friend told me about it. She said she had 4 miscarriages and then started taking baby aspirin a day from the time she wanted to conceive to the day she had her baby. I get light headed a lot and my memory sucks. When I had my last mc I bleed like crazy for 3 days then it just stopped. Lots of clots in it. Does it sound like I have this disease. I would love to ease my mind before the new yr if anyone has any advice.
