I did! I started having contractions at 10pm, only they were 2 weeks early and I thought it was Braxton Hicks. DH went to bed and I said "Be there soon, just going to the bathroom". I ended up spending the whole night until 5am next morning alternating being on the loo and passed out next to it having contractions while DH snoozed away in bed! It was my first time and I had no idea what to expect but I didn't expect that! By the time we got to the hospital at 7am I was all 'cleaned out' and dilated 2cms; so to answer your question, it all happened at the same time for me.
