Irregular vaginal bleeding between periods and pelvic pain

Patient: I am a 22 year old women who’s been sexually active since the age of 15 but with the same guy for the past 7 years. I’ve been getting a yearly pap test with nothing irregular showing up. For the past 2 years i’ve had a non-stop pain close to my left ovary and I’ve had it checked and nothing again. Now I have irregular bleeding between periods and after intercourse sometimes. What does this mean?
