Have you asked the doctor about an infection called "groub B strep" (shortened name), my sister lost her waters at 19 weeks and had her baby die at 28 weeks when delivered, there is treatment for this if caught early enough, if you dont ask they dont usually test for it, all women carry it but only becomes pronounced in some pregnant women an causes problems, it is worth looking into, and i am so sorry for ure losses x
Hello,
This is not related to your blood type. I would encourage you to talk with the physician(s) who took care of you during your past pregnancies who may have some sense of the underlying events that resulted in your losses and can talk to you about having a proper workup. Best regards,
Dr. Downing
