When Are Progesterone Levels Checked? Your progesterone level is usually checked six to eight days after you ovulate (about day 21 of a day 28 cycle). This is because progesterone levels rise following ovulation, peaking five to nine days after ovulation. This is known as your luteal phase. After the midluteal period, your serum progesterone levels will begin to fall if the egg is not fertilized.
When a follicle releases its egg, it becomes what is called a corpus luteum and produces progesterone. A level over 5 probably indicates some form of ovulation, but most doctors want to see a level over 10 on a natural cycle, and a level over 15 on a medicated cycle. There is no mid-luteal level that predicts pregnancy. Some say the test may be more accurate if done first thing in the morning after fasting.
