If I was a JW at the time of giving birth to my now 4 year old- neither of us would be here today (including my 1 year old)- I stressed this point when i was studing the 'blood issues' last year with the witnesses.
Parakeet- my nan had the same treatment for Rh-negetive, without it my dad wouldn't be here... or me.... I believe you made a good choice, I believe I did too.
