Crowds gathered in Cardiff to raise awareness of endometriosis, a condition which affects nearly 10% of women and girls around the world.
Worldwide EndoMarch is a global event which brings together thousands of supporters across the world.
On Saturday women marched through the Welsh capital in yellow.
Endometriosis is a painful, life-impacting disease which can cause severe pain, infertility, chronic fatigue and other debilitating symptoms.
It is thought to affect as many as one in ten girls and women worldwide and currently there is no cure for it.
A wall in a Cardiff Bay cafe is home to the second 'Endo Wall' in the city.
Sunflower & I in Mount Stuart Square has an awareness wall, adorned with a yellow flower.
It has over 1000 names of those living with endometriosis and those that have lost their lives to it. It was created by Jaimee Rae, who has the condition.
Similar endometriosis marches took place in Llandudno and Swansea.
