welcome to health care magic
mam you are Rh-ve and the 1st baby was Rh+ve and you had taken anti D injection after the birth of 1st baby right,,.so no sensitisation had taken place with the babies blood..
secondly for the second time you have miscarriage
,,mam for miscarriage this is not the resaon,,it might be other causes like genetic hormonal
or your infections but not due to Rh incompatibility
no need to panic and no need to check anti body status..you can plan for a pregnancy
,no need to worry..
hope you will understand my suggestion,,
if you are still in dilemma consult gynecologist for the cause of miscarriage and take precautionary measures for not getting again miscarriage...
no need to worry about anti D status(if you have been given anti d for the first pregnancy)..
