This is an odd one. I've just found out I'm 3 weeks pregnant (about 3 hours ago - yikes). I'm booked in for a "driving experience" day in 4 weeks time where I get to drive two fast cars round a race track. Is there any reason I shouldn't do this whilst pregnant? I wouldn't like to cancel because a) I want to do it, and b) my brother and sisters clubbed together to buy it for my 30th birthday, and I would feel bad wasting it. Not to mention that I don't want to tell people before 12 weeks and I don't see how I could explain cancelling otherwise. I've checked the website and it doesn't say anything about not going if you're pregnant but is there any reason I should worry? They're not F1 cars or anything, just a Ferrari and an Aston Martin.
