I am going through perimenopause and my periods are scarily heavy. For 3 days each month I cannot leave the house. It is so severe that I have had to come put of a full time teaching position and do supply so I can stay at home on the worst days. To make matters worse, my cycle varies between 17-24 days so I cannot predict when it will affect me. I am anaemic and have migraines during the first 2 days of it most months. I have been summoned for jury service and I am panicking. The courts make provision for toilet breaks but i won't even be able to get to the court if it is one of my worst days: the furthest I go is to the bird table! Advice please.
