I've been invited to a friend's hen do at which point I'll be 6 months pregnant. It's a 3 hr drive away and involves an overnight, albeit at a nice looking spa, and lunch, dinner and a massage etc and use of all the spa pools and gym. It'll cost over £200 without travel and extras. I'd like to go but am not sure if it'll feel too much by then, and I'm also unsure about using the spa pools, saunas etc (which I usually live) when pregnant. It seems they're advised against. So I feel I wouldn't really be able to make the most of it. What would you do? Need to sort this and them decide about the wedding itself, which is 4 hours away and a month before my due date!
