Doctor: Thank you for your query.Assuming that you had your menstrual cycle 6 days ago and it lasted for 3 days and the per iod came 3 days late , now after 3 days you are again having brownish to red spotting if this right probably it is because of improper wash of the uterine lining. Go to a doctor who will do a scan and an internal exam to see the underlying reason. Your query is not complete to comment further.Hope that answers your query .Have a good day.
