SORRY TMI! But first time mum 🙈 *update*

Hi guys I know this is TMI but im a FTM lol so I’m 40w today and I went toilet and saw this? Is this part of my mucus plug or? I’ve also got very runny watery diarrhea 😭.. is this a sign of me going into labor soon?

UPDATE:

I actually got my first contraction 24 hours after posting this and gave birth to a beautiful baby girl ☺️❤️
