IUI Choices 😩

I’ve been doing fertility for about 7 months with a 2 months break in between. I was on femara and only grew one follicle, raised the dosage and still only grew one follicle. On Saturday is my day 3 and my doctor is having me do a test to see how many eggs I have because some of my numbers are low. He also brought up IUI because of that reason and because I only have one tube because of an ectopic. So here’s the thing. One session is $600 how ever they have a package that is 3 sessions for $1500. However if you get the 3 package and you get pregnant before you use the 3 you don’t get your money back. I’m kind of torn on which one to do. Have any of you done IUI and is it just worth it to do the 3 and how was your experience. I’m just over thinking because I have to choose by Saturday.
