WIll today be the day, or not?

Well I would test now, since today is the first day of your period. However if it's negative test again a few days later. I was late this month and I kept taking tests which all showed up negative. I felt nothing and I think most of it was in my head. Well my period showed up 1 week later. So just relax. If it's not this month than you still have next month to try again. Good luck.
