Ladies what would you do?

So we have been TTC for 4+ years now :( so we have been seeing a fertility doctor they did all the testing everything can back good? They did blood test, ultrasounds and last month I got done an HSG which she said "there definitely open"? " But one of the tubes was slower for the dye to come out" so she sighested 2 things.

1. Is to have a laparoscopy so she can get us on a plan that would work best for us. OR

2. Do letrozole with IUI?

I am now on provera to start my cylcle.

Please ladies what would you do??

I'm scared to do surgery but I do have to do it I will. Because it's something that I know a lot of us struggle with and would do anything to have a family.
