Water ???

So..... I just went to the bathroom, urinated, and then when I was finished more "fluid" came out. I sat there for a minute thinking I had just peed some more. I remembered reading/hearing something about if you squat and cough & it comes out it could be your water breaking. I did this several times, sometimes the "fluid" would come out and sometimes it wouldn't. It appeared colorless to me. However I have been peeing so much today so it could be extremely diluted. I put on a pad (my OB told me this earlier in pregnancy) and am laying on my left side. Haven't really felt anything but am gonna check the pad for leakage soon. Let me know what you mommas think! Also, I'm 39w4d.
