Pending colonoscopy

Hello,  I’m Sarah and have just received a positive FIT test of 149 in my sample.  I triggered the test because although I’ve suffered for years with IBS.  Lately the diarrhoea has been more frequ t and I feel abit washed out after.  Found my results on patient access app last night.  Did manage to speak to a GP as it said urgent referral for cancer screening. Which totally freaked me.  Any e else had a similar story and it was polyps or something benign?  I feel sick so worried  

TIA
