ftm 39 weeks start of labor?!

Ugh.. i think my water is leaking... Last night i lost the mucus plug... A big piece just now the whole front side of my underwear and new panty liner got soaked. No contractions though. A lil crampy. I wiped twice and it was soaked. I go to the doctor at 230 so just trying to wait... Maybe its getting closer to labor??? Ftm so idk whats going on!! The leaking isnt go bad that its going down my leg and there is no smell.
