Ca-125 raised? Worried!

Hiya, I’m a 31 year old female, I’ve been suffering with bloating for a while now and the urgency to pee. 
i went to the gp on Wednesday who felt my stomach, he couldn’t feel anything abnormal… he did request a ca-125 the results came back at 50? Which apparently is raised. He’s referred me for a scan which I’m guessing is an ultrasound scan? 
My anxiety is through the roof, I’ve spoken to people and they say it’s more likely to be fibroids or a cyst? But I can’t help but think it’s ovarian cancer. 
would the level be a lot higher if it was something so serious? 
Thank you for reading
