Ivf please help

I been trying to conceive for about 4 years and a half and finally decided to go for ivf...my dr said that was the best way to go cause it seem one of my tubes is blocked so the chances of me conceiving naturally are like 5%. Anyway I’m about to start my medication for ivf and been reading and reading about the outcome of ivf and I’m sacred! It seems a lot of couples try for a few times before conceiving. So my question is ladies out there that have done ivf what are my chances of me getting pregnant the first try...did any of you?
