Any one else experienced this!?

Yes I WILL call my doctor but it's always nice to hear if an one else has gone through the same thing! I am 17 weeks this is my third pregnancy and I never had this before. For the last three days I have had a watery clear and slightly white discharge. I'm scaring myself into thinking its a slow leak in my waters but has any one else has a very watery discharge and it was nothing abnormal? Thank you in advance for any help!
