Opting for IVF, and I’m very nervous

Hi all, my husband and I have been TTC for 3 years and we have decided to go for IVF. I am really anxious about it, is that normal? Of course, I’m excited about finally (hopefully) getting pregnant and having a baby that I’ve been praying for but at the same time I’m a bit scared about it.. I suppose it’s the fear of the unknown, the what if it doesn’t work and i of course, I want to make sure I’m doing everything right, but I’m scared I’ll mess up, a lot of these stresses will be on the person carrying the baby. Has anyone gone for IVF or treatment and felt this way?
