Help please

Ok ladies this is the first time that i have put anything on here before. I have been dealing with a ovarian cyst on my right ovary since April of last year, and i was told by the emergency room doctor it is 3cm. I just need some advice on what i need to tell my obgyn when i go and see her next month and if there is anything that can be done and if i am still able to have children. I dont have any children at this time. Im about to be 31 soon, and me and my husband having been ttc for 5 months now and im just getting angry and wondering when is it going to be my turn to have a child.
