How is that possible?

I saw a mom on here comment "I knew I was pregnant because of my discharge" how could that be possible? She said she had eggy white discharge. Isn't eggy white discharge mean your ovulating? Not that it means your pregnant? 😂🤷🏻‍♀️ so now she has the poor girl posting thinking she was pregnant because she also was having egg white discharge. Btw, I wasn't bashing or judging I was just confused that's why asked is that even possible, like I wanted to know if anyone can answer that is it possible to know your pregnant by that way that she claimed.
