I suffered a miscarriage in my second trimester during 20weeks. Did my blood tests after 6 months of miscarriage and found I am Lupus Anticoagulant positive whereas my Antibodies IGg is negative. I am now 6 weeks pregnant and have seen the Rheumatologist. He said he couldn't recommend me to take Heparin since Antibodies are negative. He has made me take another blood test for the same. I am very scared if it happens to me all over again. I cannot bear the loss of my first child to go through this all over. Please suggest me if I do need to be under Heparin if only I am Lupus Anticoagulant positive. Please help.
