Hello, My name is Meriandy I am 16yrs. old & i donated blood 2 months ago. Only because i was very curious to what my blood type is because my mom is O- . & It turns out I am O- because my card from my donation came in today. My mom told me it is dangerous to conceive with someone that has the same blood type. She said this because her & my dad are both O- & my mom always had to get some strange shots because of this. as she told me. Therefore i just want to know is it really bad to conceive with someone that has the same blood type as you. does the baby come out with effects or health problems?
Hello median, Be relaxed. If you consider the risks involved to the baby, then marrying someone with Rh+ Blood group may be a problem. Its absolutely no issue to marry a person with -ve group.  Take care
