Hello TabA. Do let us know what your "doctor" says. Floaters like people come in all sizes and shapes. Some move a lot, some move very little. If they are right in front of the retina they are very hard to ignore because of the sharp shadow they project on the retina, if they move forward towards the cornea they are easily ignored because the shadown is faint. Floaters associated with retinal detachment tend to be showers or clouds of black sooty ink like particles, often with bright flashes of light (usually at night and with eye movement), loss of peripheral and/or central vision.
I believe it most likely that your examination will confirm a benign vitreous floater.
