People in the UK who are over 30, single and childless, do you feel like time is running out for you to have kids, or you would be content to never have them?

I am in my early 30s, single and have no children. I have known for a long time that I want to be a parent. I now feel more strongly about it than ever before. I feel as though it’s particularly important for me as I am effectively the last witness to my own family tree. I have no siblings and no other close family members except my parents. I feel I am in a good position as I’m ever likely to be in to have children. I am very secure financially with no debts, and I am also fine physically and mentally. I also feel that while I have a good life generally, it won't feel complete until I have children. I used to imagine myself having at least two, but at this point, I think just having one child would be amazing - certainly much better than not having any. Unfortunately, I have not yet been able to meet the fabled ‘Miss Right’ to have a relationship with, which would enable to me to settle down and have kids the traditional way, as most people aspire to do. I also know that it’s generally accepted that men don’t have really have a biological clock, and are still able to become dads well into their dotage. I have a couple of issues with that. I think that just because a man can have kids in their 60s (and beyond) doesn’t mean it’s a good idea, or something to be recommended. I would be concerned about not being around to see any potential kids grow up. I also don’t particularly like the thought of being a geriatric dad. I think 35 is pushing it for a first-time dad, while 40 is getting into geriatric dad territory. As I edge closer to that age myself, I have found myself contemplating alternative parenthood pathways. The most obvious non-traditional option seems to be adoption. I know very little about it though. The biggest concern for me is that I might not love an adopted child as much as I would my own biological child. I suspect this is true for a lot of people, which is why adoption isn’t something they would consider. Is there anyone else 30+ who feels like time is running out for them to have kids? Is not having children something you think you would be able to accept?
