I Got It Partially Right, ((( Smiles )))

My mom is AB- and my dad is B - though my sister said she was told he was AB- long ago but my mom said B- to me.
Her mother must be AB- too I just assumed she was A- because long ago a nurse at a hospital said she had A - blood and
she could give me some because I was very weak at the time and I said no at the time because accepting someone else's blood could be risky, so I declined.
But my sister is AB - and she has symptoms of dystonia so she said I must have that blood type too.
And I was diagnoised with dystonia decades ago and just found out that dystonia is more common in a group of people in the AB blood type.
I had no idea about this.
Until I started researching on blood types so I'm not totally sure what blood type I am.
But I was diagnoised with dystonia and my type seems to be very rare and I was wondering why that is???
Then I found out this.
Does that make a difference in this poll?

Plus what about the rhogham shot when it comes to negitive blood types because most people are positive.
Do they just automatically give them to negitive blood type women??
My husband is negitive too but found out they gave it to me when I had a failed pregnancy long ago unknowingly..
I found it written on a piece of medical paper long ago.
They never asked if my husband was negitive they just gave it to me anyway.
I don't think I got it while pregnent but nobody asked me about my husbands blood type. So not quite sure??
Plus I never thought about it before because I had no idea about the mercury and additives within those shots.
I went to all my prenatal visits and was under a doctors care.
Do they do it anyway just because most people are positive blood types?
Could they have done that to me too?

My edit was in adding this thought.
