Watery

Hi everyone, New to the group! Im confused and need help... I was due for my period yesterday still have nothing today. Starting this last Monday I was feeling nausea on and off with alot of bloating throughout the week. Starting last night I have had alot of clear watery discharge that soaks my underwear.... felt very nauseated last night, and now this morning when I woke up too. Is this is sign of early pregnancy, period just late, or has anyone ever experienced this?? My boobs have also been very sore since Monday and throughout week have got more sore.
