What causes luteal phase defect?

ANSWER

The luteal phase is usually about 12 to 14 days long. During this time, your ovaries make a hormone called progesterone. It tells the lining of your uterus to grow. When you get pregnant, your developing baby attaches to this thickened lining. If you don't get pregnant, the lining eventually sheds, and you have a period. A luteal phase defect can happen to you if your ovaries don't release enough progesterone, or if the lining of your uterus doesn't respond to the hormone.
