Are these baby snails?

I noticed my snails laying eggs a while ago on the glass so I haven’t been cleaning the glass to try and help some of them hatch, well now my glass is covered in tiny white specs that leave trails like snails do, (a clean path of glass behind them) they are tiny , pin head sorta size , I can’t see any details on them at all and i haven’t had much luck trying to get a shot of one on the microscope either .
They’ve been on the glass for 2/3 weeks at least now, I’m getting more and more of them but they don’t seem to be getting any larger

Edit: they are larger then pin head, biggest ones are maybe 0.75mm diameter blobs on the glass

They look like foraminifera if I had to guess
