Cervical Cancer...

Does anyone have an experience with cervical cancer? I felt a lump on my cervix a couple months ago and I felt it again a few days ago and it’s appeared to get bigger. I have researched due to being terrified and it could just be a cyst. But, I do sometimes have pain during sex, irregular periods, and pelvic pain. (I have made an appointment to the gynecologist for October 26th) I know there might not be symptoms and I most likely don’t have cancer I’m just worried.. thanks in advance
