Normal discharge or freak out?

Alright, so I’m 17w3d, and I’ve had a large amount of yellow, jelly like discharge. I know that throughout pregnancy you lose bits of your mucus plug and it regenerates until you’re ready for labor, but I’m kinda spooked and just wanna know if it’s something i should go to the ER over or just shoot my OB a text and see what she says tomorrow when the office opens.
