Hello. I have gone through your question and understand your concern. It is a well known fact that missed or scanty period can be experienced after a great stress. So relax, to rule out pregnancy take up urine pregnancy test at home. If pregnancy is not the cause then most likely cause of scanty bleeding is stress or an underlying pathology like thyroid disorder, reproductive pathology, anemia. To know the cause of scanty periods consult a doctor and undergo diagnostic test like ultrasound scan of abdomen and pelvis, thyroid profile, complete blood picture. Good luck. Hope your concern is answered. Thank You.
