If you have ever donated blood or had blood work at a dr's office or lab they should know. It should be in your medical chart.
I donated blood a lot and when I was pregnant they told me it was really important to know because you could need a transfusion. Anyhow, I'm B+. My hubby is O-.
If you know your blood type, your parents blood type, and your spouse's blood type you can figure out the likelihood of your children's blood type. For example:
My mom is O positive. I don't know what my dad is, but in order for me to be B he has to have B in him. So my dad can either be AB or B. In order to have O blood both parents have to have an O factor in their blood. Since my mom is O and my father gave me a B. My blood type is actually BO. My partner is O negative. So our children will have a 50% chance of being B or being O. The positive or negative (RH factor) is determined a different way.
