opinions asap before i call doctor

so my due date is today. i lost my mucus plug yesterday... i went to work and as i was vacuuming at 11:30am i got a small gush of something it, it was enough to soak a spot on my underwear and pants... i dont think it was pee as i didnt have to go because i just went like 15mintues prior... so i put a pad on and comtinued working for 30 minutes checked and is was damp not super wet or anything.. i continued my day... around 6pm while i was vacuuming again i got another small gush of liquid... cleaned up in the bathroom and continued to work... well its now almost 9pm and my back has been in constant pain... it doesnt stop... took a warm bath... didnt stop... could i possibly be in labor?

update: water broke in labor! contractions 2 minutes apart and strong!
