This might sound kind of gross... but I have a weird popping sound when I get gas... It is just the gas passing around the baby.. but when I lean forward I hear a *click click click*. Then I have a nasty fart. ugh!!! I never thought being pregnant would be this gross? Also, when I turn over my hips/pelvis pop. It's just the bones popping because there is so much weight down there that they are not used to supporting.
I havent had any popping sounds coming from my belly but I have heard the same thing about the popping sounds coming from your belly could be your water breaking.
I read an article about your water breaking... If you aren't sure if your water broke and you would like to find out, it says to put on a fresh pair of clean panties and lay down for 30 minutes. When you get up, if they are dry, it did not break... if they are watery... it is possible that it did. Of course, it could just be your mucus plug showing up...
