Mines never came out and I still went into labor my water never broke either and I was in active labor I lost my plug hrs into active labor and they broke my water when I was 10cm cause it wouldn’t break on its own and it was time to push
Mine could have been missed so easily if didn't develop a weird habit of wiping and checking every time I went to the bathroom. It ended up looking like a thick mucus snot with a little tinge of blood. It was 3 week before due date
