Since you are 38 years old, there is a chance of conceiving, but there is a small risk that the child may be abnormal. So, once pregnant, you should undergo a battery of tests: Triple Marker Test, Malformation scan of
fetus, and if required, Amniocentesis. Also get further investigations like Glucose Tolerance Test, Anti Cardiolipin antibodies, Lupus anticoagulant, thyroid profile, ANA, DNA, TORCH (IgG, IgM) and hysterosalpingogram. These tests are to find out why you have aborted so many times so that appropriate treatment can be started.
