Hi everyone, bit of a grim topic, but I've been getting this gross thick yellow discharge, almost like a fanjo booger 
not itchy or smelly. My GP tested me for gonorrhoea and chlamydia which we negative. She told me to use a thrush treatment which hasn't done anything. I am going for a colposcopy on Friday which I'm pooping myself about. Will they be able to tell what the issue is? Has anyone else experienced similar?
