I am currently on a 4WD trip around Australia, and we are travelling on corrugated roads in the outback, that result in the car shaking quite intensely at times. Its kind of like being on a vibration machine.

I was wondering if anyone knows how dangerous this is in the first (or any) trimester? I know that horseriding is dangerous, is this of the same nature?

Your help would be greatly appreciated as if it is not recommended, we will change our plans.

Many thanks
