IVF anniversary gift.

My husband told me he wanted to do Ivf for a anniversary gift. He knows I'm broken up about not conceiving yet and the fertility doctor gave us the option if we wanted it. Thing is its so expensive and I don't want to go through our savings on trying and possibly having it fail. I told him I would like to do a couple of more cycles of letrozole and if nothing by Nov to start looking into IUI. I can do soooo many cycles with iui and it will still be cheaper than 1cycle of IVF. I love that he wants to make me happy but I just think it would be better and yes cheaper to not jump that far. We've only had 1 cycle of treatment but it was a couple of months ago due to our schedule and timed in course.
