Anyone else diagnosed with low protein c disorder

I just started having my 4th "chemical pregnancy" all ending just about the same time, just under 5wks. I also miscarried at just over 7wks in September.

My dr has order all kinds of test to find out why I can not keep a pregnancy. All have come back fine except my protein c is low. They are ordering a retest in 2-4wks to make sure it is not a false positive. The only info the nurse would share at this time is... yes if it is a true positive it will be why I can not hold a pregnancy.

Any other ladies here with this disorder and have a successful pregnancy? I need a little hope since I fear I have very little left and starting to become depressed. I also don't understand why I did not have problems in the past with my 3 other children.
