I was diagnosed with factor V Leiden before I got pregnant. I am currently 38 weeks pregnant, and have never had a miscarriage nor have I had any VTE events. Even though I am only heterozygous and never had a clotting event before, it is apparently recommended that I be induced at 39 weeks. Who recommends this? Is the risk that high for a person to have to be induced at 39 weeks for a person who has never had a thrombotic event before? See answer

Do I need to go and see a hematologist to get on blood thinners, or is there really nothing that they would do since I only have the one copy? Also, if I have one copy does that mean that my father has two copies of it or could he possibly have only the one copy as well? See answer
