I was in the same situation. I had salpingitis isthmica nodosa and severe endometriosis Scar tissue in both tubes, one partial and one full block. After 3rd or 4th HSG done they were able to open the tubes and see full free flow of fluid. If the blockage is towards the middle they sometimes can cut the part of the tube that is blocked out. If your insurance pays for this I would ask the DR what the chances are and what they suggest. I chose to wait a bit since I was young at the time.
i'm not a Doctor but in same situation. I would suggest if ur husband sperm counts are better than go to laproscopy and then try ur own or IUI. if low count that IVF.
God bless u
