What is your blood type?

I've literally gotten blood work done at a doctor's office once, and I've donated plasma at least 20 times, but neither of them could tell me my blood type. Why is this so hard?

I am O positive.

I'm O positive, my best friend is O negative, and my neighbor told me hers is RH negative. I had to look it up, but...

I mean does anyone actually know this? Because I don't.

How many different types are there? I never even know. I heard somebody say AB, B4, and O. I think there's a lot of different ones.

I'm a bee.

NANYA! NANYA!

I don't fucking know.

I really can't remember but I'm pretty sure I'm B positive.

A negative and I absolutely hate it because every time that I'm pregnant I have to have a shot and every time I have the baby I have to have a shot because of my negative blood type.
