Paninigas ng tiyan

Hi mommies! I'm currently on my 38 weeks and 3 days now. Tanong lang mommies, possible ba na manganak or mag labor kahit di naka experience ng mucus plug or dugo? Pero always may brownish sa panty ko as in everyday. Today kasi mommies panay paninigas ng tiyan ko, as in every 5-7mins natigas sya then may kasamang sakit sa puson. Thanks po sa sasagot! ☺
