Marriage counseling AFTER you pay for the license?

My fiancé and I got our license 2 days ago and I recently got a hold of my past minister, and he said he was going to do counseling. The counseling is fine with me, but I'm confused on what to do about the license because we paid $100 without counseling when we could've paid $35. I've never heard much of counseling so I don't know how many sessions there are or anything.. I'm honestly pretty nervous, because we have a tight schedule with my fiancé working Mon-Thurs from 7 am to 6 or 7 pm and then I'm having to take care of my son with another on the way... I really need advice and some suggestions.. I hope I'm not the only that got in this position lol
