Birthing classes

Okay, so I’m a little late. I’m 30+4 weeks today and I am going to a free standing natural birthing clinic to give birth. This is my first pregnancy and I have been scared and looking for birthing classes but they’re all so expensive. They want nearly $400 for a birthing class that covers a natural birth. I have looked on YouTube but it doesn’t help and my midwives have gave me recommendations but they’re all so expensive and the one I finally found that was in my price range i was told wasn’t good. And not only that they’re mostly all online! So I’m just wondering if any other mamas have done an all natural birth outside of a hospital and can recommend some price friendly birthing classes online?
