Strange symptoms

Hi all,
So I usually get my period on time every month and it lasts about 4-5 days or so. This month it came right on time and I bled for one day, no cramps really other than some bloating.  My breasts hurt really bad and are very tender.  They start hurting on the day of my bleeding. We have been ttc for over a year.  I am nervous about taking a preg test for fear it will be negative.  Can this be a sign of pregancy?
