I had Sex with my BF around 1 month ago, we used 2 condoms, one over another. Now, I had my Period date before 2 weeks ago but it missed. NOW white semi liquid is coing out of my Vegina. No smell / oder from the while liquid

AM I pregnant? I tested at home & the result was negative. does this white liquid type thing come out just immediately you become pregnant?

if not why this is happenning.
