water broke or what can it be?

I'm really worried that my water broke or something. I'm 19 weeks and today as I'm walking out the movie theaters I felt something running down my thighs and I touched it and it was wet I ran to the bathroom and there wasn't much on my underwear as to how much was running down to my thighs I don't think I peed myself I would of felt it 🤷🏽‍♀️ what can it be? Should I go get checked?!?! Is it normal? Help
