Possible TMI. I'm scared, but can someone help with advice on what to do???

Maleah • 21 year old Mama of a beautiful girl. She will be two in Dec 2018. Currently hoping on baby number 2!
I'm 20 weeks tomorrow and Today I went pee and when I wiped it was Really gooey and I looked at the toilet paper and there was this whitish gooey thing it wasn't super huge but it wasn't my normal pregannt discharge. It was like I blew my nose from being really sick. I'm scared was this my mucus plug??? Or part of it or what? I'm concerned :( no blood.
