I was a dub when I gave birth to my son more than 30 years ago. I was so naive and uninformed that the possibility of hemorrhage never entered my mind. I was lucky; the birth was uneventful, medically speaking.
But my son would have been endangered had the elders in my KH had their way. Earlier in my marriage, I had a miscarriage. The doctors found that I was Rh-negative and advised me to accept an injection of Rhogam, which would prevent the Rh-factor from damaging any future children. Rhogam is a blood-derived medication that protects future Rh-positive children from the dangers of mental retardation and physical defects resulting from the Rh-factor. I took the injection.
Although I met with general disapproval from the elders and was actually hissed at by a "sister" for taking the injection, the ever-opening-and-closing WTS window regarding blood-derived medications was at that time open. That is, it was a "matter of conscience" and not actionable by a judicial committee. The "window" snapped shut again just a year or two later.
The sister that hissed at me was also Rh-negative and refused the injection. Her daughter was born with borderline mental retardation.
Yet another way by which mothers and children are endangered by the WTS's lethal blood policy.
