Mucus Plug? 🤔

I’m 30 weeks today and when I went pee this morning, I felt something slimy coming out so I quickly wiped and saw this.. Is it my mucus plug?? I’ve had no bleeding or cramping. But, the day before yesterday I peed in the afternoon and my discharge was a little snotty (like this but half the amount) and it was a small bit of pink. It stopped tho so idk 🤷🏼‍♀️ I have a doctors appointment 2morrow at 9:45am so we’ll see what he says. Thanks for any information ladies! 🤗
