MUCUS PLUG!! DO I GO??

I just woke up due to contractions starting yesterday & getting more intense through the night...

Just now I went to the restroom after having a bad contraction in the middle of my sleep..

Slowly noticed a dark brownish spotting in the toilet so I continued to wipe myself until it was clear and then my mucus plug came out like this.

Does this show as part of it? Is the color normal?

Should I go hospital ASAP or wait until contractions get more consistent and wait until my water breaks?
