Hi,
So you have had a
missed abortion and are spotting from 9 weeks.
You do not need to take Anti D (
RHOGAM) and do not need to worry about
RH factor as yet. The reasons are..
Anti D (Rhogam ) is not given in abortion less than 12 weeks .
Anti D is most effective 72 hours after sensitizing event(Abortion,
fetal death,delivery ,trauma to abdomen), but can be given upto 10 days.
Also, before you worry so much, I would like to know your partners
blood group, if he is also
Rh negative you need not worry at all.
Even if he is Rh postive but heterozygous to Rh there is a 50% chance that your baby will Rh negative and you will not need Anti D.
It is not at all dangerous for you to get pregnant. You can consider getting pregnant as soon as you are mentally and physically ready.
You could inform the obstetrician in next
pregnancy and she could check fetal Rh by a technology called Cell-free fetal DNA. If this confirms that your baby is Rh negative, then you don't need extra monitoring. If this shows the baby is Rh positive, she could monitor you and inform the neonatalogist when baby is born. Also take Anti D then after delivery if baby is Rh positive.
Hope this helps.
Regards.
