Hysteropingagram

K
Has anyone had this test done ? Was it worth it ? What were the results? I have been ttc for 13 months now, we tested husbands sperm and he is fine,  had an ultra sound and they found a cyst but said it should go away in 3-4 months . This hysteropingagram might be the next step to make sure everything is okay. Please tell me your thoughts.
