Hello,
Thanks for posting your query.
You can marry her but there is a risk of she getting aborted due to a condition called Erythroblastosis foetalis.
Your wife needs to take a Anti Rh-D
antibodies before you plan to conceive.
So you can consult a physician when you plan to conceive and proceed accordingly.
Hope I have answered your query.
Wishing you good health.
Regards,
