Hi and welcome, This is a common myth that couples with same blood group have problems. On the contrary they do not have any problems due to blood groups. Problems come when the mother is having a Rh negative group like A -ve, B -ve, O-ve and so on and the father is a positive like A +ve or B+ve and so on. In this case the babies may have severe jaundice if the baby is Rh +ve like the father. When both the parents have same group, or the mother has Rh +ve group, this problem does not arise and baby is safe. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
