He Swapped My Baby,I Left Him with Nothing

While cleaning my son's room, I accidentally found his blood donor card.

The blood type was listed as B positive.

But my husband and I are both type O.

How is it biologically possible for two Type O parents to have a Type B child?

I took the card to my husband.

Carter, who had always been a polite gentleman, flew into a rage instantly:

"Our son is already in college! What more do you want? You're paranoid all day. Did you stop taking your meds?!"

I insisted on a DNA test.

He slapped me hard across the face twice, slammed the door, and locked me inside the house from the outside.
