I took mine a few days before I turned 28 weeks

I wonder if mine does! that would be pretty awesome! I'm 2 days away from the second trimester so I'm looking to get in already.

A lot you can take almost right away. My town had a class that you do every other week it talks about the different stages and if you take all the classes you get a free car seat at the end

I think it's when you're a few months from your due date to start the the information you've learned is fresh in your memory.
