Mucus plug with brown discharge

First time here. Ask lng po, kninang umaga nilabasan nako ng mucus plug na parang gelatin at my sumunod pa na prang sipon. Pero after nun minsan lng ako makaramdam ng cramps. Kelan po kayo ako mag aactive labor na to? 2cm po ako kahapon kanina chineck 2cm padin pero nalabas ko na yung mucus plug. Sabi din po kasi nila basta lalaki daw pasumpong sumpong lang yung cramps. Anyone po na nakaexperience? Currently 37 weeks and 4 days.
