Booger like discharge.. normal?

I’m 23 weeks.

Yesterday I had a booger like discharge.

Kind of light yellow/light green and it was in a ball about the size of a large pea.

It’s like a big booger.. sorry tmi.

I figured I shouldn’t worry about it but then I have had 2 more since then.

Everything I’ve read said it might part of my mucus plug.

Should I worry?

UPDATE:

Called the doctor to be safe and she said it’s totally normal as long as there is no bleeding/cramping.
