Can different blood groups of the partners lead to illness during pregnancy?
Patient: My blood type is O+ and I was married previous and my pervious husband also was O+.  I was pregnant for several  times and I never get sick though out my previous pregnancies.  After I got divorce I got remarried for a new husband and his blood type A+ and we decide to have a new baby then after I get pregnant I became very sick, I was having high fever, vomiting a lot,  and tireless which I never had this symptoms before. My question is since my new husband and I have different blood type is that the cose of my sickness? Doctor: Hi,No a different blood group should not cause you to have such symptoms. A different blood of a new husband could probably give you a slightly increased chance of high blood pressure, and pre-eclampsia in the later part of pregnancy.Fever, vomiting and tiredness, could be a infection unrelated to pregnancy. You should see a physician and get get blood test to check for infections and take medicines for fever and the other symptoms. Do discuss the safety of medicine during pregnancy before taking them.Hope this helps.Regards.
