Watery discharge

This is how my discharge has been the past several days I'm 31 weeks I have an appointment Thursday so I'm going to mention it then but it feels like I'm leaking it does not smell like urine it's watery with mucus like discharge any one have an input or personal experience? Is it normal?Also it'll leak through my shorts yesterday I noticed I had a wet spot on the outside of my shorts in the crotch from this

Side note the little black dots are fuzzies on the inside of the pocket just so ya know
