Losing mucus plug after cramps - 33 weeks

I’m currently 33+1 with my second. I know losing pieces of the mucus plug doesn’t really mean anything as it can grow back, but lately I’ve been losing a lot of it.

It’s never been bloody but for the past 4 days in a row I’ve lost multiple chunks of it varying in size from a dime to a quarter following an episode of pelvic pressure, lower back pain & period-like cramps.

I never went into labor myself with my first (induced at 41+4 & I was at fingertip dilated & not effaced at all when I got to hospital) so I’m not really sure what I’m doing here lol.

But with the pressure, back pain & cramps... it has me a bit concerned.

Is this normal?
