No children being born during the Tribulation

Jesus spoke about the difficulty pregnant women and nursing mothers would have in fleeing from the anti-Christ at the beginning of the Great Tribulation, which is the last half of the 70th Week. (Matt. 24:19) This alone would suggest that mothers will continue to give birth during that time.

Matthew 24:19

How dreadful it will be in those days for pregnant women and nursing mothers!

The only other talk I remember seeing is of “the birth pangs” but that is specifically speaking of the “buildup” of the tribulation

This may help as well. It more so shows how a post tribulation rapture would be incorrect and that the Bible teaches pre tribulation rapture
