Hello, my periods are generally 4 days long with moderate to heavy flow. In November I missed my periods after doing panchakrma (ayurvedic body cleansing) and my gynaecologist gave a pill and my periods stated after 4 days of pills. Now last month my periods were on time but lasted only for a day and this month my periods are very light /scanty and lasted for 2 days. I am 40 years old and never had period related problems ever.
