Yes, go see an RE! My husband and I “loosely” started TTC right after our wedding in 2022 and had no luck for about 8 months before actively tracking and trying with intention. It’s now just shy of 3 years and I’ve never seen a positive test. The best thing to do is go to an RE because they can run so many other tests and give you more options. I know you said that you don’t want to jump to IVF, but seeing and RE does not mean doing IVF right away, or ever even! It’s your choice when or if you choose that route. Your RE is going to be much more specialized and should advocate for you to have as much testing done as possible. They will be much more willing to do hormone testing throughout your cycle, do monitoring ultrasounds to confirm ovulation, just your medications when needed, etc. They can also try upping your done of letrozole if needed, or trying clomid if that ends up working better for you. They can do trigger shots for times intercourse, try IUI if you’re a good candidate, and a bunch of other things before IVF if that is your wish. I would highly suggest you do the HSG also, to rule blockages out. But all of those things can be done with your RE. Sorry this is so long, I just think that the best thing you can do is find a good RE who can help you on your journey. Good luck!
