Let me be straight forward here for a second. I sincerely hope you don't mind me being blunt, but it's for your own sake.
I'm not a doctor. I've not attended medical school and the last time I watched Dr. House was almost a year ago therefore I cannot answer your question.
Even if I was a doctor I would still have no idea about your particular case without all the results.
Even if I had those results and papers, I would still only be able to take an educated guess, that either you should keep trying or simply give up.
Would you believe me if I said go on, keep trying? What if I'm a jerk and having a laugh.
What if I told you to quit trying to conceive. You'd probably don't believe me and keep trying anyway.
Here is the deal: If you really want to hear a professional opinion, ask your doctor. Or ask any doctor you trust for that matter. Have yourself checked and when you get an answer, accept it as something you've been looking for.
Personally, without being a doctor all I can say is to attend regular examinations, cysts are nasty stuff, and probably keep trying. Even if it doesn't happen, you still had fun meanwhile.
Ps.: Its not aimed at you personally, don't take it as such, but I don't understand why people consult with internet about their health. Hello? It's the internet with lolcats and weebl's stuff. What do WE know?
