NO PIC JUST QUESTIONS mucus plug

I'm a FTM and all night I've been having heavy menstraul type cramps, but no upper contractions. Just sporadic cramping. Well twice now (once earlier in the night) I've wiped away HUGE amount of.. Well.. goop. And I mean, if I wanna be grossly specific, a hand full each time. Like when your man cums in you times like 6. No blood. It's yellow ish and super sticky.
