Pregnant? Idk really know..

So I've taken 3 pregnancy test this past week but both have came out neg but the weird thing is that I've been having like egg white watery discharge and a lot of it and when it first happened I googled it and it said it was a early sign of pregnancy and and the discharge has been on and off for the past 3 days so far, this has never happened to me and I should be starting my period in three days but I'm just worried and don't really know what to do?
