Nope! Not while a jw, but I did donate for the first time last year. Congrats, btw! It's a great feeling, isn't it?
The fact that you can't donate if you've spent 72 hours in prison gave me pause. *Must never, ever commit a crime!*
I've donated twice so far and would have done so a third time, but I had had a Yellow Fever vaccination too soon prior to the last time the blood drive came by.
Funny thing - my mother travels with her "no blood" card and I travel with my "blood donor" card. har!
