Progesterone levels during ovulation have a crucial impact on pregnancy. During ovulation, a woman's progesterone levels peak and gradually decrease over the next few days. If a woman's progesterone level is only 2.54 during ovulation, then this may mean that she is experiencing early pregnancy difficulties.

There are many reasons why progesterone levels may drop. One of the possible causes is irregular menstrual cycles in women. If a woman has a shorter menstrual cycle, she may have lower progesterone levels around the time she is ovulating. In addition, a woman's diet, exercise and stress levels can also have an impact on progesterone levels.

If a woman's progesterone level is only 2.54 during ovulation, she may need to consult a doctor as soon as possible. The doctor may recommend that she get a blood test to determine if her progesterone levels are within the normal range.
