All through my teens I thought I really wanted to be a mum ( I came from a big family), then after a miscarriage at 18 weeks at university I realised I was too young, had so many career and educational aspirations, travel aspirationsect. My partner has always said he doesn't think he wants kids but wouldn't rule out one. However the older I get (I'm in my 20's) I realise I enjoy not having to be responsible for anyone but myself and want to do so many things in my life where kids just don't fit in. I still get broody but not to the point where I must act on it right this instance. Many of my friends have one if not multiple children and the stress they're under along with not being able to put yourself first gives me anxiety. I'm the eldest of five and feel I spent a long time helping raise my siblings especially the youngest. I am looking to gain a doctorate in computational biology and eventually want to work for the likes of nasa. Is it weird to say I will put off kids til at least 30 and then at 30ish re evaluate my decision? Has anyone else had similar situations, (I'm not bothered that if after 30 it turns out I'm infertile, I will just look at adoption if I decide its time to have children at all.
