Fertile cervical mucus question

I’m not sure how to phrase this, but do you ‘pass’ your egg white cm?

Since learning how to track my cm and cycles, I’ve noticed that once I do my cm check and see the egg white cm, that’s the last of it until my next cycle. I’ve tried checking multiple times after and it seems like once I pass a big glob of it, my fertile window is closed and my temps rise the next day.

I’m still safe of course and follow the three day dry rule, but I’m just curious about the mechanics of it.
