Amber
 So today at 39+4 I had my cervix checked I'm thinned out with no dialating at all about 1 is when I had it checked no spotting nothing after the exam then randomly tonight at about 10:30 a full 9 1/2 hours later I wiped and had mucus with brown blood in it is this normal or would you say it's my mucus plug?? This was all their was nothing else and when I wiped a second time their was nothing it wasn't loose like period blood it was just in with the mucus
