I'm about to go and visit my cousin, and I always ride when I go there. However, being nearly 6 weeks pregnant, I'm thinking that falling off a horse might not be a good idea. I need an excuse not to ride that won't make her suspicious!
Any ideas for, e.g. a bad back problem that might have sprung up over night (I didn't think about this in advance, so it needs to be a last minute problem!)
