Did my water break or did I pee!?

Kat
I just woke up and my underwear were soaked and there's a little spot on the bed. I also just had to get up and pee a bunch in the toilet. Would you think that if I'd peed the bed I would've like noticed or let it out? I can't tell if it smells like pee or not. Also, on Monday I was told I was 1cm dilated and 50% effaced. I really have no idea what to do I'm confused
