It's just a biological clock One, so very important for the creation of a life within you, a part of you. Why shun it or view it with disgust and shame? Just be proud and blessed to be given the privilege to create a beautiful, tiny bundle of joy because of this regular cycle. Hola Writos, Today is World Menstrual Hygeine Day (MHD, MH Day in short). It is an annual awareness day on May 28 to highlight the importance of good menstrual hygiene management (MHM). It was initiated by the German-based NGO WASH United in 2014 and aims to benefit women and girls worldwide. The 28th was selected to acknowledge that 28 days is the average length of the menstrual cycle and with a period of 5 days hence 28/5.
