Mucus plug or discharge?

I’m 38 weeks and I’ve started seeing a lot of mucus. It’s like the more I wipe the more there is . It has a yellowish tint with some clear mixed in. I saw a spot of blood in some and it’s stringy. I’m not sure if this is parts of my mucus plug coming out or if it’s just some sort of discharge . It’s been going on for a few hours now .
