Keep losing mucus plug

This is my second pregnancy & I know the mucus plug can regenerate but I keep losing pieces of it. I’ve been losing chunks about the size of a quarter since 26 weeks. I’m 29+1 now & on top of losing pieces of the mucus plug I’ve been getting a lot of pelvic pressure.

I had an elective 3D ultrasound at 28+3 & baby was very high up & completely transverse so I don’t know if the pressure is just from him trying to turn around the right way?

Is this something I should bring up to my doctor?
