Fluid smell?

What does the fluid smell like? I've had this clear like fluid with a little discharge kinda trickle out & I'm thinking it's just cervical mucus bc the doctor did say that I had a lot which was normal she said. I smelled it & it sort of doesn't smell like anything I can't really tell idk. What does the fluid smell like? Or how can I differentiate the fluid from CM? Some say bloody show might occur but I've read that some women don't get the bloody show.
