33 weeks mucus plug?

Melody

I've been having painful tightenings on and off and today a large amount of goop came out of me. Like palm sized.

Here's some that was on the toilet paper when I was wiping it off.

I've read if it's a mucus plug it can regenerate if it's before 35 weeks but I'm 33 so close to that. I've some small punts come out before and not worried. Just concerned because of the amount.

What do you think??
