Hay, mommy, ang dami talaga ng discharge at backache at 39 weeks kaya malakas ang possibility na ito na talaga ang mucus plug, lalo na kung notice mo na may iba ang consistency or may slight color compared sa normal discharge mo! Since closed pa cervix mo last check, it's really a sign your body is preparing na, kaya best mag-check ka na with your OB agad para sure na at para malaman kung may changes na sa cervix mo ngayon, baka naman opening na siya and you're closer to labor than you think!
