Sure. But the problem is when the specific stories being told about regret or changing one's mind prop up stereotypes. That's why I said I'm particularly annoyed by stories that portray a woman's choice not to have children as a selfish mistake.

Or, here's another way of looking at it. I'm reaching the age where I'm pretty sure I'll never be a doctor. It's not impossible, but my age and the amount of schooling involved means that it's no longer likely. That's a regret that I have.

I'm probably going to see ten "regret over not having kids / not prioritizing romance or family" plotlines before I ever see a "regret over choosing a different career" plotline.
