Mucus Plug (Sana My Nakapansin)

Is this my mucus plug? Aint sure kc lge nmn ko ngkakaron ng vaginal discharge (white and not sticky) , but this time ang sticky nia, ang thick nia unlike sa normal discharges ko. Im 39wks and 6days. No contractions, no pains yet. Sana my makapansin, salamat. What to do?
