Thanks for the advice. Even though I am making a plan now, I also intend to go with the flow, don't worry
When I was a member of another forum (one of the apparently "better known" ones) I asked the same question and got such negative advice it got me really down. The advice was things like "oh midwives don't even begin to discuss a birth plan until at least you are at 36 weeks" etc. So glad I left it!
At least I can trust the advice given on here....
