Thanks for the query.
There are many causes of recurrent abortions, and you should get investigated accordingly, and treated too.
Most common cause is chromosomal anomalies - you should have the chromosomal testing of previous abortion tissue, and if not done, then get your couple karyotype.
Also, tests for immune causes - for antiphospholipid antibody syndrome - are important. They include a battery of tests such as antibodies to antiphospholipids, coagulation tests etc.
Uterine abnormalities have to be ruled out by ultrasound now, since she is pregnant, else a hysteroscopy
is ideal. Sometimes, the mouth of the uterus ( cervix ) is loose, hence that needs to be seen in ultrasound
ALso, some infections are implicated - such as toxoplasmosis
, rubella, herpes etc, tests for those need to be done.
Basic investigations such as blood grouping, viral markers. thyroid tests, blood sugar testing, testing for thalassemia
, urine tests should be done.
Appropriate pregnancy support, as prescribed by your gynecologist should be taken, particularly progesterone support, if progesterone deficiency
is suspected as a cause.
Go for regular antenatal check ups, have regular scans, take all prescribed medication, have enough rest, avoid stress.
