[|AI|]  Hi, dairy have gone through your question. I can understand your concern. She has thrombophilia. She has tendency of blood clotting.  It leads to pulmonary embolism.  You should take warfarin to avoid it.  Keep your INR between 2 and 3 to avoid clotting.  Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
