Is this my mucus plug?

Sav

I’m 39 weeks and 5 days pregnant and got this today. There was more on my underwear and in the bottom of the toilet. Last time I was checked I was 1cm dilated. Yesterday I had blood in my discharge but I’m pretty sure that’s from being checked 5 times in one day. I’ve been having irregular contractions that aren’t very strong.

After this I got more the next time I peed but there was a lot more this time. I couldn’t get it all on one piece of toilet paper. Does there have to be blood in it to be my mucus plug?

And now every time I pee there’s more but it’s small and there’s small chunks at the bottom of the toilet. 🤔
