Abnormal menstruation

Patient: My menstruation was 15 days late. i have always been regular so far. today is my 12 day of heavy bleeding with clots. i am a flight attendant for 14 years and 41 years old. please advice

Doctor: This irregularity at most times is related to stresses, tension, ingested medications and caffeine. Remember that fluctu ation in periods indicates the beginning of disturbance in the natural chain of hormonal events that manage menstruation. Hope this helps.
