Had my c125 and it came back at 37

Hello just wanted to post to see if anyone has been in the same situation as me i suffer with health anxiety and so always think the worst. 

I had a c125 test due to frequent urination and a bif of pressure in my pelvis. 

My c125 came back at 37 and I'm worried.. I was on my period on the test. My gp has referred me for a non urgent scan she said my test was likely borderline due to period or fibroids (which my mum had). But i can't help but worry! 

Please help
