Hi
Thanks for posting your query on HCM.
It is unfortunate to know that you had a
miscarriage.
Incomplete data like what was the duration of your
pregnancy (gestation)?
Was it a spontaneous miscarriage? What is the
blood group of your husband.
Anti-D injection is not required for spontaneous miscarriage before 12+ weeks of gestation, unless there is instrumentation or medical evacuation of the
uterus.
Anti-D injection is also not required if you're certain that your husband is also Rh-negative.
It should be considered in women if there is heavy, repeated bleeding with
abdominal pain as she approaches 12+ weeks of gestation.
So, if your gestation period was more than 12 weeks you need to take the Anti-D injection.
Visit your treating doctor with the lab result and seek his or her opinion.
Hope these information could be useful to you.
Best regards.
