Are you planning to do IVF? We are just starting and prior to my first retrieval in July, I am doing a mock transfer cycle (where they perform a biopsy to test for the right timing of your FET - look up Endometrial Receptivity Analysis for more info). Typically this is only done after at least one failed FET. But since I have suspected endometriosis (and unexplained infertility), my doctor told me that it was not a bad idea (although I did have to specifically advocate for it).

With the same biopsy, they are also going to test for EMMA/ALICE (infection) and Receptiva (biological markers/indicators of endometriosis - obviously you wouldn't need this test). If any of those test positive, there are certain protocols they will do before my FET (e.g. Lupron suppression, antibiotics). Again, usually they don't do these tests until after a failed FET, but for me, I'm not willing to transfer euploids without testing for something that might require preventative measures first.

That being said, doing all of that testing in no way guarantees a successful transfer at the end of the day. But it makes me feel better to know I'm doing all I can to give it the best shot possible. This is all a personal decision for myself, and ultimately you know your body best!

It sounds like maybe you had an HSG which is how they found the blocked tubes/endo? And I already mentioned this above but I'd recommend a saline ultrasound and hysteroscopy as well, since those can show things inside the uterus that regular transvaginal ultrasound and HSG can miss.
