Thanks for all your replies girls!

There does seem to be a fairly standard pattern so it seems I am going to fortnightly appts a couple of weeks earlier than the usual 30 or 32 weeks. I actually think Christmas will get in the way of my 'first' fortnightly appointment anyway.

I guess I'd like to have as little intervention as possible and it seems like the more appts I have earlier in the pg, the more likely intervention will be. Maybe I am being silly. I have no drama going more frequently at the end of the pg and will probably prefer that but the idea of needing to be seen more often to discuss pain relief seems silly to me (given my preferences) and is not based on any earlier discussion for him to know my preferences or the reading I have already been doing for myself. Feels a bit sausage factory I guess.
