Is the Menstrual Cycle Taboo Where you Are?

Annabel Croft is a former British number one tennis player. She says the menstrual cycle is the "last taboo" for women in sport and that women "suffer in silence" on the subject. Her comments come after British player Heather Watson admitted feeling unwell during the Australian Open because of "girly things". Should sport talk about it more openly? Has it affected your performance in sport or another area of your life? And why is it still such a widespread social and religious taboo for so many people around the world?
