Birthing classes

Dee
Long story short 
I'm 34 weeks pregnant I want to sign up for birthing classes with my hospital the only issue is that my SO won't be able to attend due to his work schedule. 
I don't have any friends/Family where we live and I don't really feel comfortable going with anyone in his(they're nice but I just think it'd be weird or they'd be negative)
Do you think it'd be dumb if I went alone?. 
More should I just not go?.
Thoughts please
