Could Discharge Of Water Along With Contractions Be Due To Labour?

Hello I'm 36 and 4 days ..2cm 50% I woke up this morning at 2am with pain. Then realized my underwear and shorts were wet like I voided on myself. I then us the restroom and laid back down I had contractions for about 3 hrs until I fell asleep . By 9am I stopped leaking and all day had contractions . Maybe 3an hour...I'm not sure on if I should go in or wait . There wasn't a smell
