Ovulation Based On Temperature
By tracking your basal body temperature each day you may be able to predict when you ll ovulate.
Ovulation based on temperature. Then 24 hours after the egg s release your temperature rises and stays up for several days. Your temperature will probably stay high. Before ovulation your bbt may range from about 97 2 to 97 7 degrees fahrenheit. The bbt method requires charting your basal think base body temperature when you re completely at rest.
Ovulation may cause a slight increase in basal body temperature. But the day after you ovulate you should see an uptick of 0 5 to 1 0 degree in your bbt which should last until your next period. Then just before your period starts the hormone progesterone drops. You may notice your temperature occasionally spiking on other days but if it doesn t stay up you probably haven t ovulated yet.
If you want to determine when in your cycle you ovulate tracking your basal body temperature bbt is a good starting point. 1 it remains higher throughout the two week wait. When you ovulate the follicle releases progesterone which raises the temperature about one degree. This happens in the second half of the menstrual cycle when there is a noticeable rise in temperature right after ovulation happens.
You ll be most fertile during the two to three days before your temperature rises. Your basal body temperature changes based on a number of factors including your hormones. Bbt is the lowest temperature your body reaches in a 24 hour period. Your body temperature dips a bit just before your ovary releases an egg.
During ovulation your body releases the hormone progesterone which brings on a slightly raised temperature a day or two later usually by 0 5 degrees. Before ovulation a woman s bbt averages between 97 f 36 1 c and 97 5 f 36 4 c. It usually works well. In turn this may help you determine when you re most likely to conceive.
Why does temperature rise after ovulation. The rise in temperature can be a sudden jump or a gradual climb over a few days. By charting the differences in one tenth degree increments you can determine when ovulation has taken place. When you ovulate the hormone progesterone causes your temp to rise.
Anywhere from 96 to 98 degrees fahrenheit orally is average before ovulation. For most women 96 to 98 degrees is considered normal prior to ovulation and 97 to 99 degrees after ovulation. However it may not be as active as once thought. After ovulation most women have an oral temperature between 97 and 99 degrees fahrenheit.
In women bbt follows a biphasic pattern throughout the menstrual cycle that is it s lower in the first half of the cycle. Usually a woman s basal body temperature rises by only 0 4 to 0 8 degrees fahrenheit. Prior to ovulating the basal body temperature ranges from 97 to 97 5 degrees fahrenheit although some women have slightly different readings from this.
