O-, as is my dad, one of my brothers, my ex-dh, my two eldest kids. However, my dh is not, he is one of the +'s...so after three miscarriages and subsequent anmio when pregnant with dd, I had my share of rhogam shots...yuck. Dd is also postive I just can't remember which. But, I can give blood to both of them in need be.
BUT...after decades of giving blood, it looks like I may have to stop. It seems the Red Cross has massacred my veins. Twice I've been to the hosptal to have tests done, and when they have tried to take blood, found it very hard to get a 'good' vein. That was never the case with me. I may just give platelets from now on though.
