Lupus anticoagulant

Amy.
Has anyone been diagnosed with lupus anticoagulant after miscarriage. I have a daughter that just turned 11. I had no problems with her. We have been trying for 7 years and conceived in October but I had a missed miscarriage in December. My doctor did blood work and the test for lupus anticoagulant came back evaluated. I seen the hematologist yesterday and they did more blood work. Has anyone experienced this?
