re: How many abortions are result of mother's health?

The time that would be to protect the life of the mother would likely be an ectopic pregnancy and that would be terminated prior to 12 weeks. That's a legit reason.

If the embryo implants in the Fallopian tube, then that could rupture as the baby grows and cause the death of both mother and child. The choice is not one of the mother's comfort over the baby's life, the choice is then to save the mother do you sacrifice the child or do you not do anything and risk both lives. It's a different thought process altogether.
