Probably not, to be honest.
I my case, I wanted children so if I hadn't managed to have them, I would have been miserable, because I would have had a very rosy view of what life with children was like.
But knowing what it is like, if I had a second life, I probably wouldn't, because whilst there is nothing specifically wrong with my children (I have 3 teens/tweens), and there are nice moments, I think my level of happiness has been significantly impacted by everything that comes with children, and generally speaking, I feel the nice moments just don't compensate for the rest - especially now they are out of the primary school years, which were very much the golden years (so basically you get about 10 good years!).
I had had significant heartache and worry trying to manage being an involved parent with having a career (I now have a 'semi career', which has plateaued because I didn't take on the big global roles which would have involved significant travel.
Also let my health go to an extent, in that I exercised a lot less, and probably slept a lot less, trying to be present with them and take them to all their activities etc, whilst trying to work full time (so basically ended up working most evenings to catch up). I know I can get that back when they leave home, but would have been more enjoyable to have it in my 40s than in my 60s!
All my life revolves around them, be it catering to their needs when they were little, nagging about homework and fighting about screentime now - and watching in frustration when they don't put in half the effort that I do for their studies, for instance.
I fantasise about being able to just focus on me. Do what I want of an evening, exercise as much as I want, read a book, watch a film I want to watch - and especially, not have this constant worry in the back of my mind of whether they are going to do well in their exams / whether they are happy at school or need to change school, etc etc (whatever the worry of the moment is - and i haven't had any serious health concerns to worry about!).
I also feel slightly used. My headspace is taken up by them, and I put so much in, but one child will repeatedly say that she intends to leave home at 18 and can't wait to do that (she is 13), another one in an argument yesterday about constant scrolling said to me 'nobody wants you here anyway'. I know it was said in anger, but when you are standing there doing the family ironing after a full day's work, then it does hit hard.
In your position, I wouldn't worry too much about the kids, but I would develop a hobby which you really get into and gives your life a purpose, and occupies you and which you can build things around.
The main challenge my sister (who has chosen not to have kids) has found is that a lot of her peers do have them, so her husband and she can sometime struggle to find friends to go away on holiday with, for instance, as everyone else is doing family holidays, or to meet up during the day at weekends. So she is looking forward to all her friends kids going off to university so her friends will be in same boat as her and more available. But that is a minor inconvenience in the grand scheme of things!
