Do I have floaters?

I have had several ophthalmologists tell me they don’t see any eye floaters , but I have been developing spots in my vision. The largest is a dark area about the size of a cooking spatula at arms length. The dark area Is always present even when looking at dark objects like asphalt or closing my eyes. I also have about 20-30 other smaller random shapes of varying opacity. All of the spots move together when I look around. Eye doctors can’t find any problems with my eye…. I am 26 years old with no prior health conditions other than -6.0 myopia. This started about a year ago.
