I was set to start my period Monday or Tuesday. I have had some light brown discharge that turned a light pink and then stopped but it was only when I wiped. I've had mild discomfort but nothing like my normal period. My period is extremely heavy and painful but regular. So this is extremely abnormal for me. I have been dizzy, had some slight sensitivity to smell, and been slightly nauseous but nothing that absolutely makes me stop and think I'm pregnant. I don't want to waste money on a test and get my hopes up. Is this just a late period or should I buy a test?
