Need Your Advice please, Eggs In Our Tank???

[I cant find Nemo]

Hello.
We have found 3 small clear circular things (about 3mm diameter) on the glass of our tank. Each circular thing has 5 yellow/brownish dots in them. We were told that they could be Cory eggs but after doing a search on here and looking at the pics, we are not so sure.
Can any of you's shed any light, have tried to take a photo, but have been unable to so far

Thanks
