Induction tomorrow but... did my water break?

How do you know if your water breaks or if it’s just pee... I was squatting down helping my husband with my son in the bath and I coughed and had a huge gush come out of me and I didn’t feel like I peed but I was coughing so I very well could have. Then I went into other bathroom to check and I did pee so maybe I just peed some when I coughed because that can happen but how do you know? I wouldn’t normally question it but I’m this close and have had a few false labors over the last few days and it felt like more than a trickle like I get when I sneeze sometimes... like how do I know...
