Is this part of my mucus plug?!?

I forgot to flush (pregnancy brain) and needed to pee again (don’t worry that’s all I did last time I used the restroom) and saw something! I got an old toothbrush (it’s in the trash now) and scooped it out. Sorry if grossed out I did that but dang I needed to know 😂

Is this part of my mucus plug!? When I wiped I saw a creamy smear and thought hmm doesn’t look like others pictures and I must’ve overthought which led me to forget to Flush but I’m glad I did because I saw this!! I’ve been having constant back pain and my butt hurts too! I was 1cm dilated a few days ago and VERY low baby. I’m currently 38wks1day.
