How come "pro-life" doesn't include the mother's life?

Respectful of Otters just posted a piece about so-called “partial birth abortion”. It cites an article in Ms. about a woman whose baby died in utero at 19 weeks. She was forced to spend a week carrying a dead fetus inside her – bleeding steadily, at risk of hemorrhage – before she could be treated. Quite simply, no-one was willing to treat her, because the safest procedure for removing the fetus was proscribed under the “partial birth abortion” ban.
