A lady had been having serial miscarriages since she got married. She had lost four pregnancies, and each time she became pregnant, she would start antenatal care early, take her medications and follow her doctor's instructions, yet she still couldn't carry the pregnancy to term. After the fourth miscarriage, she was referred to another doctor who decided to run more tests on her and her husband, including their blood group and rhesus factor. The woman was O negative while her husband was O positive. The doctor explained that being Rh negative does not mean a woman cannot have children or that she will automatically have miscarriages. The concern is that if an Rh negative mother carries an Rh positive baby, fetal blood can sometimes enter her bloodstream during pregnancy or delivery. Her body can then become sensitized and produce antibodies against Rh positive blood. Those antibodies can cause complications in a later Rh positive pregnancy. The doctor also explained that anti D immunoglobulin can help prevent Rh sensitization when it is given at the appropriate time during pregnancy or after certain pregnancy events, such as miscarriage, bleeding or delivery, depending on the circumstances. The woman had never been told any of this during her previous pregnancies. She became pregnant again and this time received proper monitoring and the necessary treatment. She eventually had a healthy baby. What shocked me about this story is that many women know their blood group but have never been told their rhesus factor or what it means for pregnancy. And this is where I think we need to talk more about it. Are you Rh positive or Rh negative? If you are Rh negative, did your doctor ever explain anti D injection to you during pregnancy? And for women who have experienced rhesus incompatibility, what was your experience? Please share your experience. Someone reading the comments may learn something that could help them.
