Should I try IVF?

Trish • I am 37 years old. I`ve had 3 pregnancies but no kids. When I initially downloaded this app I was 34.
I've done <a href="https://glowing.com/glow-fertility-program">IUI</a> twice with no success. I'm considering an <a href="https://glowing.com/glow-fertility-program">IVF</a>. I really do have the money but I want a baby more than anything. My boyfriend is on the fence about it and could careless if we ever have kids. I'm sure we will only do this once so if it doesn't work I don't know what will happen. What's the likelihood I'll get pregnant on the first try?
