Leaking amniotic fluid or discharge?

Kayla

I am worried but not sure if I should be...I have always had a lot of discharge but it is typically more white and I typically don't feel it coming out. Today, it has seemed clear and runny and while in the store I actually felt it come out which is unusual. It felt like I peed a little and being that I am 30 weeks along I would normally assume that it was pee but I had just used the restroom. Any thoughts? Should I be concerned?
