How much mucus plug can a girl have !!?

Jasmine • Expecting our 3rd due February 5 2019

I have had 2 membrane sweeps one on Monday and another yesterday. And since Monday I have been loosing it. Every time I go to the restroom I have BIG chunks. When does it run out?! I never had this much with my other 2 kids . I remember I had maybe 2 big chunks and that was it . And with this one it’s constantly coming !
