Ay oo, normal yan mama! A few of us dito sa community experienced the same, the mucus plug can come out days or even weeks before labor kicks in, kaya hindi sya sure sign na magsusulong na agad. Since wala ka pang sakit ng puson, it's likely your body is just preparing, pero definitely contact your OB para ma-confirm kung lahat ay okay lang, especially to rule out any infection or complications, mas peace of mind lang yan para sa inyo!
