I had no show, nothing at all. I felt "weird" all day previous to the birth and around midnightish felt I needed to pee (but nothing) and 3 1/2 hours later my little man was born, so nope you don't necessarily have prelabour and if I did I didn't notice it. I think about an hour after thinking I needed to pee (got up about 3 times in an hour...lol) I was actually contracting at around 4-5 mins apart! Forgot to say... my waters didn't even break, they did this at the hospital. I felt I needed to push before leaving home, so probably a good thing they hadn't broken..lol oh and didn't tell DH this until after birth
