I know when my plug fell out when I was pregnant with my son, it was real thick like ovulation discharge with a mix of blood. And....Your water can take up to 2 weeks after your plug falls out before it breaks, if it even does. Mine didn't, my dr had to break my water. Hope this helps!
When u loose your mucus plug it should be mucusy with a ting of red blood you can start to loose your plug as early as 28 weeks an nothing can happen you may just be getting extra discharge it happens in late pregnancy
I though I lost my mucus plug at 34 weeks because I had discharge with a bloody show for about 2 days....And then the discharge was a lot for the rest of the 3 weeks. I went into labor at 37 weeks but my water never broke.
