last year for guy fawkes DH and I went to our local funfair and fireworks display and thoroughly enjoyed ourselves. We want to do the same again but I'm not sure what, if any, rules there are about rides if you're pregnant? Our local funfair rides are relatively tame so we're not talking the big rides at Chessington here. Is it okay to go on things like those twirly shells or similar? [I will be 11 weeks at that point]
