TMI: watery discharge!?

I wasn't sure what group to post this in, but here I go. since about the middle of my second trimester I've been experiencing a little water discharge, like every other day. i am now 27w 4d. I looked it up online and it said it can either be hormones, leaky bladder, or leaking amniotic fluid. I keep forgetting to mention it to my OB. I'm not bleeding, cramping, or anything unusual. this is my first prepregnancy, and don't know if it's normal or not. I have an appointment the 15th for my OB and I wrote down notes and questions to mention to him. but i want to know from y'alls experience if I should notify him sooner. thank you in advance :)
