"Yo" = "your"
"Your clock" = your biological clock (that registers your age)
"Your clock is ticking" is an expression that means you are getting older, and refers to a womanīs ability to have children that lessens as they age.
Many girls in their late 20īs and throughout their 30īs will say, "My clock is ticking" as they fear they will not be able to have children.
