No stranger on the internet can answer this question for you. It's one of the biggest decisions that any person can make and only you can make that decision about what is right for you.
We can only give our own perspectives so here's mine:
I know and understand the feelings of uncertainty on this issue. For some people, they've always known either way what they want or indeed, don't want. For others, it's not so straight-forward.
At 19, I was in the camp of "I'm never having kids," and I was true to that statement for sixteen years. I never wavered once, but once I turned 35 and my nephew was born, I started to question and doubt my position.
I started to wonder what life would really be like with a child. Would it really be as bad as I'd originally thought for all those years? I looked at my brother and my SIL with their baby and started to wonder if that was something I wanted for myself after all.
I went so far as to choose a nursery for my future potential baby, looked at baby names, etc. In the back of my mind, in a little voice that I was trying to drown out, I was having new, fresh doubts about my new decision to have a child.
Do you really want to lose your freedom to a child? You know that stack of unread books over there will never get read if you have a kid-you'll have no time! You can't stand listening to kids screeching and crying and being kids. How will you cope with a kid, 24/7? If you have a kid, your life will revolve around that kid. No more easy days on the sofa. No more get up and go. No freedom-my inner voice.
The more I reflected on the reasons I allegedly wanted children, the more I realised that I didn't. I may have wanted the good, fun, cute bits that kids can sometimes bring with them, but I definitely didn't want all the other stuff. The stinky nappies. The chaos. The noise. The restrictions placed on my life.
I asked myself what I would do if something went "wrong." How would I cope, for example, if I became a single mother? What if the child has additional or special needs? How would I cope then? I thought about all the ways that my life would change, even if I had the "ideal" child and I knew it wasn't something I wanted for myself.
It's one thing caring for someone else's child for a temporary amount of time, and entirely another being a parent. Many people get themselves "conned" into having kids because they've babysat kids/babies before and found it ok, and then when they have their own, they realise what a vastly different experience it really is. When you're babysitting, you always know that you're going to give the kid back. As a parent, they're yours 100% of the time. No refunds, no returns and no exchanges.
I realised quickly that I was trying to convince myself to have a child because it was what my family wanted for me. I knew that if I really wanted a child, I wouldn't have to talk myself into it.
The hard bits about having a child are worth it if you really want a child. They're not if you don't really want one and only had one to fulfil societal pressure or to alleviate FOMO.
I've always found the concept of FOMO to be a rather funny thing, really. In life, there are always going to be things we miss out due to decisions that we make and we shouldn't base our major decisions on FOMO. There's the possibility of regret whatever choice you make-I just know I'd rather regret not having children than regret having them.
As I said at the start of my very long post, it's a personal decision and one only you can make. If you can't see your life without kids, then maybe that's a clue that you do want them. If you can see your life without them, well, that's also a clue.
