Hello everyone. I am hoping some of you lovely folk can help with something. 12weeks pregnant with 4th baby, all other pregnancies been fine, but threatening miscarraige with this wee baba, and also possible twin, but only one baby there now. So i have been given the all-clear thankfully, until today, when midwife rang to say antibodies in my blood. She wondered if i ever had transfusions, no, havent. So they believe its my husbands blood that is causing my production of antibodies. All our other children have been fine. So why now? I am rh positive, hubby rh neg. He has had issues with his blood in past few years though. Please anybody have an inkling what might be going on? Or experience in such matters? Hubby for blood tests in 2 days. We just have no idea on what this could be. Worried worried worried.
