Thank you all for your replies, it was interesting to see different opinions

I was thinking more of the 'after the baby is born' part, not so much about the 'planning a pregnancy' tbh. As someone said the questions are for me to answer as i have to look at my own circumstances.
To respond to Amy, I think what you say is, would be the correct answer, ignore society/who cares about society, save enough money = wait for the perfect time= make enough money= work hard. These are of course only my interpretations. I am at the stage where I need to choose between what is correct and what is correct for me, and that makes a huge difference.
I think i 'work with scarce resources' e.g. money and time constraints. My own thinking comes bit in the way, eg. I want to be a mother before the age of 30 but at the same time when i think about money it never seems enough and whatever I could save I spend it. (I do not spend it on clothes, shoes etc but I save for a deposit, but once i have it, i spend it on a property and take a mortgage, so basically I spend it.) I think I am being realistic here, I do understand I need a fair bit of money in the coming years and I try to secure my future so I never need to worry about how i will pay the mortgage, whatever happens. Also business seems very slow recently for me, and while i understand i could probably advertise more to shake things up I don't think i actually want to as i am also building up another career in the way and also study and therefore reduce escorting.
I also consider moving to another country where my money i have would be enough to live my life without debt. However, infrastructure, lack of healthcare etc seems a big compromise in those countries i looked at so far. Therefore, as I put it I have to manage what i have, the scarce resources, and even if it seems irresponsible to some, to decide to have children while having no solid foundations (financially). And yes, this is self employed job however the nature of job is unusual with the stigma attached so I not only have to consider the self employment aspect, but what society says about it.
Sorry if my post doesn't make sense I am in mess pretty much but do hope you guys understand where I am coming from.
ETA: even to me i just realized, seems that I have a plan (before 30) but I ran into problems with the execution.
