Will you support Endometriosis UK to #EndoTheStigma by taking on the 1 in 10 challenge? This Endometriosis Awareness Month we are asking our supporters to join in the 1 in 10 challenge to support the 1 in 10 with endometriosis. The money you raise throughout the challenge will go a long way in helping us support those affected to get the support and healthcare they need.
