In brief: No progesterone

The ovaries produce estrogen during the first half of the cycle to stimulate the growth of the uterine lining.
After ovulation, they produce Progesterone to mature and stabilize the endometrium for implantation. At the end of the cycle, the ovaries stop making progesterone, causing the lining to become unstable and shed as menses. Thus, if there's no ovulation, then no progesterone, and no period.

In brief: No Ovulation

When your period is late and pregnancy tests keep coming up negative, the most likely explanation is that you did not ovulate.
When you don't ovulate (or release an egg) your hormones are not coordinated and you skip a menstrual period. This can normally occur once in a while or could be a sign of a longer term problem.
