Lottapianos " think she's far from alone in her thinking"
you mean you think a lot of people absorb those messages?
It's funny how I'm mellowing in middle age 
if you'd asked me when I was 25, I'd have said "oh well, if you can't think for yourself"... but as I've grown older and met more people I've realised how much that message is pushed.
is it mostly about control of women or something, I don't know. The really stupid thing about this so-called biological clock is that women can and do have children up to menopause.
also when she came off the Pill she was shocked to get pregnant quickly - and she wasn't the only person I know who thought that. how does anyone square this with "miss one Pill and you risk pregnancy"?
it was a really weird time...shocked she was pregnant even though it was planned.....pissed off throughout pregnancy, ragingly angry and drinking heavily immediately after the birth....after it went on a few months my mum wondered if she was hoping the DP would just go off with the baby.
anyway, this is too depressing so I'll stop now.
but yes, OP, if you don't want to have children, don't have children, it's all fine!
