My period is acting weird . I came on , on friday , dec 5 . It started off very pinkish spotting . On saturday it was pretty normal , bright red , regular flow . On sunday it was brownish as if it was ending . On monday (today) it started off still brownish , spotty , & as the day goes on its getting more redder & heavier and im crampy . This isnt normal for me . What could this mean?
