Hi everyone

im new here and this is my first post. My gp has referred me for a transvaginal ultrasound due to a variety of symptoms (excessive bloody or brown discharge - so heavy that I have to wear panty liners which is completely unusual for me, different types of pains, unusual/unpleasant smell). My biggest concern is cervical cancer.

I just wondered, is there a standard practice for next steps if nothing is found during a transvaginal ultrasound? Will the patient automatically be referred to gynaecology for more tests? I ask because I've read from multiple sources (including this forum) that a transvaginal ultrasound doesn't usually pick up on cervical cancer? I'm worried that if nothing is picked up on during the ultrasound I'll just be told nothing is wrong and be given no further tests, which will cause so much stress and worry in case I do have CC but it's just not been found. 
I haven't seen my GP in person due to covid restrictions (only spoken to him on phone). 
Has anyone else been through this and can tell me what the average procedure/protocol is? Thanks so much in advance. X
