Leaking Fluid Whilst Period Leaking? Worried, Please Help?!?

Leaking? Worried, please help?!? - leaking fluid whilst period

I thought you might be pregnant, I'm on my 3rd Day of my period of absence, but I have two pregnancy tests yesterday and both came out neg, and one of the morning, which was also neg.
Today I noticed right out of the tub and clear / white fluid coming from my vagina, I was not depressed, or was something of fluid and could not stop, so it s not like I was leaking urine or something. Then I noticed that sometimes when I think I fled, and when I changed to 15 minutes after leaving for about 10 seconds. (sorry if its TMI).
Who knows what is and could do with the pregnancy, or why I lost my time? "
Thank you, any help appreciated
