Going off of what I vaguely remember from Biology last year, I think babies start to develop nerve endings during the second trimester and wouldn't really feel pain before then.
Late abortions are cruel, but it's either that or another forgeted up family.
Yeah, to add to this for XR-7, Most abortions accurate in the first trimester, when the fetus is still VERY tiny and can not feel pain.
People who are against abortion tend to automatically think all people abort late ,which is rarely the case.
