You will still be able to do a lot of stuff! There are a lot of tame rides and walkthroughs. There are a few coasters that you probably wouldn't want to go in, but there are plenty of other things!
There are only four "roller coasters" at Legoland. There is a lot to do even pregnant. Most rides will be okay, and theirs still the shows and Lego mini City etc.
That's the thing about legal and there is so much to do for everybody no matter how pregnant you are so hurry fun and great place to visit
Probably only a few rides/coasters you couldnt do. But most things will be fine
You could go on most rides, pretty laid back rides rather than extreme as set up for under tens generally. Probably 4 or 5 not suitable (if that)
Most of the rides are very mild. I think you would be able ride on quite a few.
There are several rides that I would consider ok to go on while pregnant, though I'm not sure what the park's policy is.
