Is getting pregnant "contagious?"
We've all witnessed that "It must be in the water" effect when it seems like everyone around is getting pregnant all at once. In neighborhoods, in schools, among close groups of friends...
What do you think causes this? Women's cycles tend to sync up, so do you think it's something like that?
I would say it's just following our peers... but often it happens without us even knowing at first!
Do you know what causes this? Any speculation?
