What are my chances?

Hey ladies! I have PCOS and 1 blocked tube. In my last follicle tracking scan after taking my second round of clomid, i had 1 good sized follicle on my right ovary. My left was very polycystic... But it's my right tube that's blocked! Should i be worried? Can i still get pregnant? Been trying for 4 years now!! I'm so fed up! It just seems to be one thing after another!! 😭 
Do you think i'm likely to gave an ectopic pregnancy if i ovulate from my right ovary?
