Birthing class conundrum

So DH and I were supposed to go to a birthing class last Saturday, but it was rescheduled to this Saturday due to snow. Unfortunately, we can't go this weekend because we are celebrating DH's birthday a month early with two shows in NYC. The next class is scheduled for my due date and I can't find classes anywhere else. This is my first baby, but DH's second, and I am now way more nervous than I was before.
