Really worried about CA 125 results

Hi. I am 43 and for the last 2 moths have been going back and forth to my doctor's thinking I had a urine infection as I have needed to go to the toilet a lot more than normal. My urine tests have always come back normal and so I was referred for blood tests. My CA 125 level has come back as 39. I am not sure if that is really high or not but have now googled and read it can be an indicator of ovarian cancer. I  am booked in for a ultrasound and a transvaginal scan this Sunday and am terrified of what they might find. Has anyone else had a an above normal ca 125 and was it something simple.

Many thanks for reading.
