Worried! (Might be tmi)

Alyse
So today since I woke up, I'd use the bathroom and then when wiping there would be thick, clumpy cervical mucus on the toilet paper. Now it's been a long time since I last saw my plug come out since my daughter is 8 now, but I'm worried it's my plug. I have had days with this pregnancy where I'd wipe and it would be thick, but it wouldn't continue all day like today. It's not bloody, but still making me worry because I'll be 30 weeks tomorrow. So is it just normal or the plug?
