I wasn't sure how to word this...
but in the last couple of months I have had this very distinct sound sometimes... it literally sounds like water trickling or draining from my skull down my spine. sometimes it just sounds like fluid and sometimes it's more of a fizzing/pop rocks type sound. it only lasts a couple of seconds and always weirds me out.
i asked the ladies in my due date board but no one seems to be able to relate. after doing some googling, i've seen that other people have experienced it but with no real answers.

do you get this? do you know what it is? wtfffff??? haha.
