First time mom question.

I had my last "major" appointment yestersay and after my appointment I went to the bathroom and had lots of dry blood on my panties. My doc also said my mucus plug was coming out soon... This morning I went to pee and when I wiped there was a blob of brown snot? Is this what a mucus plug is supposed to look like because I was expecting something clear with a little blood but what I saw this morning was just brown. I took a picture as well but I don't know if I should post it or not. I asked my mom and she said to call my doc, she's had 8 kids and said that after she got her mucus plug she went into labor that same day or the next. Was it any similar for you 2+ time mommas??
