As a child in the 70s, I saw a made for TV movie where many white teens or young women are mysteriously pregnant. There is a scene where they seem to be summoned or are in a trance like state and they all walk toward some location in the middle of the day across some fields. I was young so I didn’t really understand the plot or I didn’t see it from the beginning, but I got the feeling that they were impregnated by aliens or the devil. I’ve never been able to find anyone my age that can recall this one. Hopefully, I’ll have some luck in this site. No, it’s not Village of the Damned.
