I never took birthing classes with either of my children.
That might sound crazy, but dad was always away working and I worked full time and I just didn't have the energy to schedule any of it. I took care of kids whose parents went to lamaze classes and I certainly wasn't against the idea, but the hospital my daughter was born in was an hour away and like I said, I didn't have the energy after work to to and then get home so late and then work the next morning.
My nurses were so good to me...they told me what to do, I had no epidural or anything with my first baby. It all worked out just fine.
I think some people really enjoy knowing what to expect and learn the breathing exercises, the different positions, etc.
I don't regret winging it.
I would look around or ask your hospital for referrals. They have lots of classes that don't cost that much. I'm not in NY, but I'm sure there are other avenues to look into. Are there classes offered through a community center or your hubby's college?
Classes or not, your body will know what to do when the time comes and you will be fine.
I hope you find something that fits better for you and if you don't take any classes, it won't be the end of the world. I have two healthy kids and didn't take classes for either of them. Their births were completely different so I just rolled with what was going on at the time as opposed to what I'd been taught. It worked out fine for me that way.
Best wishes!
