Did my water break?? 19 weeks and woke up with wet pants.

I'm embarrassed to post this, but I'm 19 weeks pregnant and just woke up with very wet pajama pants. (the bed wasn't wet, only my pants) I don't know if I peed myself, or if my my water spontaneously broke. Any other moms experience this? I'm kinda freaking out because I usually recall having to pee, even in my sleep.
