I think the social pressure isn't so much having kids but having the 'ideal amount' of 1-3 kids and fitting in. Because I love kids and I want kids when I grow up, but when I tell someone I want five or more kids, I get the "are you crazy?" look. So it probably goes both ways.
Not only is there no urgency, but everyone is much happier by doing what best suits them. There's nothing unfortunate about women feeling they don't want children. What's unfortunate is a woman pressured into motherhood because it's what is expected, even if she feels unfit or has no desire to be a mother, simply because the "she's a woman and therefore needs to be a mother, she'd be happier with children" mindset. It's an unfortunate situation for the mother and the child. If someone decides not to have children, whether an individual or a couple, respect their decision it's probably what's best for them and the would-be children.
Make your kid stay in the cage and you'll be staying in the cell
