I have had 5 days of "normal" periods and for the last 4 days, light pale brown discharge (sand color). Is this normal? I am not taking any contraception.

It is possible for light brown spotting to occur after having a normal period for a few days. This could be due to your body adjusting and readjusting after menstruation. It is normal for the menstrual cycle to take a few months to regulate itself. Irregular cycles or spotting may occur during this time.
