How do I know if I'm ovulating?

If you have regular monthly periods, you are likely releasing eggs from  your ovaries  (ovulating).

You can get information about the approximate days you ovulate by making a graph of your basal body temperature. Your basal body temperature (BBT) is your body temperature in the morning before moving about or eating.  An increase in the basal body temperature of 1/2 to 1 degree F occurs the day after ovulation and will remain elevated creating  a chart that has lower temperature readings before ovulation and higher temperature readings after ovulation. This is known as a  "biphasic" pattern.

If your basal body temperature graph shows a biphasic pattern, you are most likely ovulating.

How do I know when I'm ovulating?

You may experience one-sided, abdominal pain at or around the time an egg is released from the ovary. The pain usually lasts minutes to hours, but may last up to 48 hours. This pain is known as mittelschmerz (German for middle pain), because it occurs in the middle of your cycle.

Other symptoms you may have that indicate you have ovulated:

  • Breast tenderness
  • Lower abdominal bloating
  • Cramps
  • Moodiness
     

The typical  menstrual cycle is 28 days long. However, menstrual cycles may last from about 21 to 35 days. For women with 28-day cycles, ovulation usually occurs on days 13 to 15.You can use the calculator below to estimate your date of ovulation.
