I think a piece of my mucus plug fell out?

So two nights ago I got up to use the restroom and I noticed this blob of red mucus, my mucus plug fell out the morning of my delivery with my first born but now I'm only 34 weeks, I see my doctor Wednesday- but I've been wondering if it's normal for the mucus plug to start "dissolving" so early? I've heard it can replenish itself? Any one else had this happen?Β 
I'm not really that concerned because I have zero pains, no bleeding, no contractions, nothing. I feel great!Β
