Driving in labour = bad idea. Even strong prelabour or strong BHs. Trust me, you get a strong contraction and your concentration on the road is gone.

Otherwise I was driving pretty much until I went into labour. (With 12 days of prelabour - but only once when it actually was bothering me and not again.)

Obviously if your bump is so big you can't move the steering wheel maybe you should think about giving it up too, but that didn't happen to me.
