What does a longer ovulation cycle mean?

Longer cycles are caused by a lack of regular ovulation. During a normal cycle, it is the fall of progesterone that brings upon bleeding. If a follicle does not mature and ovulate, progesterone is never released and the lining of the uterus continues to build in response to estrogen.

What is late follicular phase?
