Could it be water leaking?!

Eithah
So it's my first time pregnant and never had this experience before .. But whenever i go to the WC i find my panties wet thu i am waering panti liners all the time and this leads to not making them stick and change every time i go to the wc :/ 
I haven't seen any different colour or any colour at all ..but my friend had her water leak since week 30 and she had no idea until it was emergency and had to sleep at the hospital etc.. 
Am in my 34 th week today so is there any thing to worry about or this could be normal?!
