Air from vagina with lots of cm?

Hope this isnt tmi, but I am only 3 dpo and this morning I woke up to a very weird sensation. It is almost like my vagina is farting when I walk around. We haven't bd for a couple of days and since I have had tons of cm. It sounds like a fart but I am just pushing out lots of clear cm. So much so I had to go to bathroom to wipe it all out. I get that sometimes during af but never at other times that I can recall. Seems like it would be too early for pregnancy sign. Just curious is anyone else has experienced something similar. Thanks
