can someone please explain this to me?

all day today i have had very wet discharge, i have thought i was starting AF multiple times (due in three days-but hopefully notđŸ€žđŸ») i have never had this happen before, it is just clear and wet...i have already tested multiple times and all negative. i don’t recall ever having this type of discharge before..thank you very much for everyone in advance, i don’t have any other people i can talk to about this or ask these questions too.
