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
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.
