Did you take a childbirth cl?

I took a cl before the birth of my first. Instead of the weekly or biweekly one hubby and I did the one that is like 8 hours on Saturday. I also read EVERY pregnancy book known to man. Hours on the internet with google, webmd, babycenter, etc, btw that was daily too. I was a little neuritic to say the least. Of course, with all that knowledge in my head i still went to hospital too early and was sent home because I came too soon (3 days!)
