Sounds like vaginal discharge. Like when your vagina cleans itself. It becomes more predominant when your pregnant
That is a long Web address and probably looks like I am sending you a scam or something.
Maybe just go to google image search and type in "inside vagina".

Lol today I google imaged "inside vagina" because I was curious as to what the doctor saw when she looks up there. There was a very helpful one that had arrows pointing to certain things and telling what they are and a discription.
There is a circular hole up there that is usually closed, but opens at certain times (period, ovulation, discharge..).
Pretty interesting to see what my lady parts look like from that point of view.
