There is no one Christian opinion now or any time history about abortion. But if you want to go with Augustine, Thomas Aquinas and Pope Innocent III early abortion before quickening was not a sin as per the two latter that is when the fetus is ensouled. That is around the middle of the second trimester. Popes Sixtus V and Stephen V both were against it at any point. Luther seems to be against it at any point.
