Help!! Mucus plug and cramping/contractions

Shamone • FTM |🎀👑👶 011817
Ok so at around 12:20am I started feeling pressure in my lower back and abdominal. Knew it was contractions because the pressure became intense and consistent. Finally after about 2hrs I feel asleep..I woke up at 5:21 with period like cramping/pressure and seen that my mucus plug had broke ( it was thick mugus with pinkish blood so I'm guessing this was the bloody show also) I am a Ftm mom but also 40 wks 3days... I have an induction scheduled to begin thurs night. Should i just wait to be admitted until then or do u think my labor will start sooner??
