The possibility that scares me is J D Vance and his ilk creating programs like the German lebensborn program that informed the Handmaid program in Atwood's Gilead.
The German Reich also went through a population implosion, but wanted soldiers and laborers for the cause, and so chose (young, pretty) Aryan women to bear kids?
Whose kids? High ranking SS officers usually had the option to volunteer. No, the women didn't have a say in it: It was voluntary in that they were compelled to volunteer.
So yeah, not only is it a bad time to have kids, its a bad time to have working genitals. Some women are getting sterilized, though you will struggle to find a doctor through mainstream healthcare channels; they'll try to talk you out of it.
Instead, look up witchy circles, lesbian circles, feminist circles and reproductive healthcare circles to get connected. You can also seek counciling at Planned Parenthood, and they'll set you up with a doctor.
Imagine being forced to have the child of J D Vance or Stephen Miller or Ted Cruz. That is not beyond the scope of reality now.
