when is ivf recommended?

Is it the last resort? We are starting ourfertility  testing next week. I ovulate and have a couple other tests done. I hope it's a simple fix and they don't recommend <a href="https://glowing.com/glow-fertility-program">ivf</a> right away. We conceived 5 years ago..we have been trying for 1 1/2😢 and advice would be great. Thanks!
