I thought your ovulation was determined by when your period started.

No. Ovulation happens when your pituitary glad tells your body to release a surge of luteal hormone. THAT releases the egg.
Your luteal phase is the period of time between actual ovulation and the beginning of your period. It will not vary more than a day, maybe two, each month. It should stay the same. A normal luteal phase is 10 to 16 days with 10 really being low. My Dr. considers anything 10 or under to be a luteal phase defect. Your luteal phase must be long enough for the embryo to implant into your uterus. Basically, when you ovulate, the remains of the follicle your egg comes from on your ovary sticks around (corpus luteum) and produces progesterone, which will support a pregnancy -if you conceive- until the placenta takes over. If you do not conceive, the corpus luteum will die off and stop producing progesterone. Therfore, if the egg was fertilized and didn't implant yet, and your luteal phase is short, there's no progesterone to support it.
Your menses, is, of course, the number of days you have your period. This can vary in number of days.
Your folicular phase is between your period and ovulation. This phase can also vary in number of days.

No, ovulation is determined by when your body releases the LH hormone, this stimulates the ripening and release of an egg. It can happen at any time in a womans cycle- since her cycle is unique to her own body.
You can monitor your LH production and test for the surge (which happens 12-24 hours before the egg is actually released) to know exactly when your particular window of fertility is.
