Sorry you are feeling discouraged ;( infertility is very frustrating and time consuming!
If you are open, you could consider trying a few rounds of iui. Even with a blocked tube you can have success. BUT I would go to an RE to do it, not anOBGYN.
The national averages for ivf success iis about. 40%. However each clinics success rates are very different. Go to www.sart.org
to find clinics in your area and take a look at their percentages. 32 is still ahead of the game if your labs are good. IVF would probably work very well for you with your IF issues. Find a reputable RE in your area and at least go to a consultation to see what they have to say.
It is true that many of us have to endure multiple rounds of ivf before achieving success, but many are successful after just 1 cycle! Best of luck to you
