Scared I can't have a baby

Me and my boyfriend have been talking about having a baby. I'm going to the gynecologist Tuesday to get my annual check up. I'm going to talk to her about it but I'm just worried if I wait any longer I won't be able to have kids. I have a history of ovarian cyst. My aunt has had ovarian cancer and my great grandmother had cervical cancer. I really want a baby of my own. I started crying at the thought of not being able to have kids. I just want to hear some of your tips or suggestions. Thanks ladies
