How many people have had IUI? I want to try IUI. But so scared to spend the money and get a BFN

I had one a year ago and was so excited that I was going to get a positive text but the out come was that I got a negative! My fertility doctor then wanted to try doing IVF but it's so expensive!

3 rounds and nothing, but my insurance covered7 rounds of IUI and 3 of IVF. If I got pregnant and delivered, the numbers reset. I got pregnant with both rounds of IVF.
