ENDO/ADENO: patients who self-reported having a diagnosis of endometriosis and/or adenomyosis. No ENDO/ADENO: patients who self-reported not having a diagnosis of endometriosis and/or adenomyosis. PCOS: polycystic ovary syndrome. Regular period Variable= (number of patients with regular periods / number of patients who have periods) x 100. Bleeding with clots: clots present in most or all periods. VAS: Visual Analogue Scale measures pain intensity. It has two end points representing 0 (‘no pain’) and 10 (‘pain as bad as it could possibly be’).
