You don't want to, no one is forcing you to abort.
The discussion here is "who is forced to do something". This child in the womb would not be able to live without the life of the mother. Therefore their "choice", if you can even call it that, is irrelevant.
(I honestly don’t have a strong stance, but both sides have equivalent arguments and what bothers me is people refusing to acknowledge that)
The right to dispose of any unwanted child the mother cannot or will not care for herself is one that, like in vivo abortion, women will exercise irrespective of whether the law permits it. Poor indigenous women in Brazil allow their sickly babies to starve all the time.
Conclusion: any society that does not allow humane infanticide within the first year is literally Handmaid's Tale.
There is an extremely negative consequence if you try to regulate a person who is a grown persons body.
I would only buy the argument of respecting a life if we also extend this to way beyond a child in the womb, and to everyone living. Until we do that, there's no excuse to control a person's body.
