Lat September while having my period I experienced excruciating pain on my right side. It was a sharp pain as if someone stuck a knife in my side. It was unrelenting for hours and I had to lay in bed and could not more. It subsided and then exactly 12 hours later occurred again. I went to the ob/gyn about a month later and they found a uterine/cervical polyp on the pap smear which they said was benign. I also had a cyst that was about 2cm and it was during the middle of my cycle and that said the lining was slightly thickened. The symptoms of achiness subsided so I did not return for another ultrasound. Now, over the past two months, I have had a lot of discomfot in my right side near my ovary, near my belly button and lower back. At times my abdomen seems to be bloated and then goes down. I am terrified this may be cancer. I set an appointment with my gyn next Wednesday but am so afraid to go. Could this be symptoms of a cyst or cancer?
