My mucus plug was a clear/yellowish tinged with white through it. Didn't have any bit of blood through it. But it started out as small bits over a couple days and then a massive clump about half the size of my palm came out. I was 38 weeks when it started and I saw a midwife and she did a stretch and sweep and then I was 3cm dilated and in early labour for 4 days before I went into active labour.

i asked my nurse the same thing and her reply was unless it has a pink/bloody tone than it isn't.
