when your blood was tested, you still had your mother's blood running through your system.
I was 4 or 5 years old at the time of the test...I remember it and still have the little booklet/blood card somewhere how long would my mother s blood run in my system?
how was the RH positive gene activated?
my cousin s changed during her first pregnancy!
when I tried to give blood at 17 I was given a new blood card now being 0 -
but I had been on the pill for a year,full strength in those days, maybe that was a trigger
