Could I have ovarian cancer and not know?

I am almost 19 years old and I have had bad bladder infections and pain in my pelvis for about 4 months now and I kept telling to doctor and they didn't see anything abnormal in my urine so they kept telling me that it was just a bladder infection and "rib cage pain". So, about a month and a half ago I had pain so immensely bad in my right side of my pelvis and when I would have a bowel movement it was ten times worse. I went to the Emergency Room and they did a vaginal ultrasound and found "multiple ovarian cysts" on my right ovary and they were hemorragic cysts. So, I've just been dealing with the pain. But, recently I've been having pain on my right leg from my pelvis down to my knee and I'm feeling full quickly after a snack along with bloating all throughout my days. Could I have symptoms of ovarian cancer and not know it? Would the doctors be able to tell?
