Discharge like a literal egg white?

18F

I usually have very minimal discharge daily but every once in a while (3 times that I recall) I'll be wiping after peeing and I'll notice this super sticky clear clump, like the size and look of an egg white. I googled it and the only thing that came up was cervical mucus and that it meant I was very fertile that day. Is it cervical mucus? Has anyone ever experienced this?
