Aquariums: Are these snail or fish eggs or something else?

Currently in the tank I have 6 Pygmy corydoras, 2 amano shrimp and some snails that got in through plants, I can identify a bladder snail and there is are some other small snails too. They are on the plant and glass

Removed most of it in a panic as I was not sure if it was a snail infestation
