Chances of conceiving...?

My husband and I have been trying to conceive for about 2 years now and about a month ago I went to the doctors office to do an ultrasound. Well it showed that I had a complex ovarian cyst. So the doctor wanted to reevaluate in a month to check the status of the cyst. Well I went back and and the cyst went down in size, but now she is saying that there is possible tube blockage. What are my chances of conceiving (naturally)? 
Any positive comments/ help would be appreciated. 
Thank you!
