Any recommendations?

My husband and I have been trying for a year now. 26F, 32M. He has a 3 year old daughter with his ex. We did 4 months of letrozole and an HSG. They think my right tube is blocked but no one can give me a definite answer. My OBGYN won’t help me anymore and told me to go to a fertility specialist. Well I had my consult and they told me it would be another $2,400 just to do some more basic testing. From there we’d be paying about $16,000 just for treatment (<a href="https://glowing.com/glow-fertility-program">IVF</a>, <a href="https://glowing.com/glow-fertility-program">IUI</a>) with medication on top of it. Unfortunately we just can’t afford that right now. We’ve t tried everything. OPKs, PreSeed, sex everyday, sex every other day. I’m getting really upset and don’t know what else to try.
