My period was suppose to of started on sept. 5th. I am late I have been on time for the past year. I started this afternoon spotting a little bit. Real light pink. Then it turned a brownish color. Can this be the start of my period. Normally I have real bad cramps the first day of my period, but I am not having any of my regular symptoms. I don't want to spend money on a test if I am just late. I don't know what to think.
