How do you know if your water broke? This is my 3rd baby and with my other 2 I just went into labor without my water breaking but I went to go pee right now and sat down and went and then I went to wipe and what I think was more pee just came out and when I stood up and wiped the toilet paper got soaked and some went down my leg and all over my underwear so I changed and put a panty liner on so I'm not sure?? Anyone have a similar thing happen and was just pee?
