MUCUS PLUG BA ITO?

Hello po, good morning! Ask ko lang po kung bloody show na ba itong pinkish discharge na ito? I'm 40weeks and 1day today. 3:30am kanina nagstart yung feeling na napupoop ako pero walang lumalabas kundi ihi lang, tapos pahilab hilab s'ya from lower back to front. Labor na po ba iyon? Inconsistent pa naman po yung time interval pero ayan nga po may lumabas na pink discharge twice na po. Should I go to my birthing center? Thank you po..
