PCO and PCOS are completely different things. There's no link or correlation that
PCO leads to
PCOS.
PCO is a variant of normal ovaries, whilst
PCOS is a metabolic disorder associated
with an unbalanced hormone levels released by the woman's ovaries
PCO is a
normal variant of a woman’s ovary, whereas PCOS is a
diagnosed condition with short and long-term consequences.
PCO is more common than PCOS:
PCO is more prevalent with up to a third of women of childbearing age having polycystic ovaries on ultrasound and no other symptoms. PCOS, on the other hand, affects 12-18% of women of reproductive age, with 70% of these cases remain undiagnosed in the community

In short- PCO is very common in women of child bearing age. Women with PCO do not have issues with conceiving.
PCO is not something to be concerned about. It is not a disease.
