Fallout shelter had an update couple days ago to fix some issues, one of them being the women are not having babies. I got the update, restarted my phone, and tried everything I can possibly think of but I still have 5 pregnant women that are not having babies. My the fallout shelter age, they maybe pregnant for like a year or two now since they are suppose to have babies 3 hours from conception. No babies and my population in the valut in current stuck......

It's because you don't have enough free space. Build more sleeping areas.

Ohhhhh makes sense. Thanks a bunch.

Usually you will see the counter in the corner with dweller numbers sort of pulsate and sort of blink, that is a indicator of you needing to make more living space.
