Is this my mucus plug pls help!!!!

I am 19 weeks pregnant and have been having these mucus balls come out when I wipe. Sometimes clear. Sometimes yellow tinged like this and one time earlier it had bloody streaks. And it has happened about 7 times now. They were all this size or larger. I am worried bc I am so early and have pressure/cramps. I sent my provider a message on the portal already but I am impatient and wanna know if anyone had this.
