Heavy Period

My friend came from Australia to visit for 3 weeks. She is a nurse in Mebourne and had had 1 vac before she made the trip. She was very late for a period, 17 days.  When the period started it stopped and started until it really got going. She had the period most of the time she was here, 3 weeks. She wears a menstrual cup so could measure the blood flow, nearly 2 litres of blood she lost. Went to a Dr here but they couldn’t find anything wrong.  When she got back to Australia, her Dr suggested she delay the second jab. She has since had the jab and had another heavy period.
