How Long After Ovulation Does BBT Rise (And Why)?

Réponse exacte: 24 heures

Basal body temperature (BBT) is a person’s temperature when a woman is at rest. Women need to track their BBT so they know when they are ovulating, with this a woman can determine when she is most and least likely to become pregnant.

The eggs are normally fertile within about 12-24 hours after ovulation. If you avoid sex for a few days after ovulation it can help prevent pregnancy. One should be aware that the cycle may change making it difficult to determine ovulation.

How Long After Ovulation Does BBT Rise?

The basal body temperature (BBT) will drop slightly before ovulation begins, that is 24 hours after the release of the egg, its temperature rises and is maintained for several days. Before ovulation, women’s average body temperature is 97 ° F and 97.5 ° F. After ovulation, it rises to 97.6 ° F at 98.6° F.

You can generally track your cycle by taking BBT every morning using a body temperature calculator or thermometer. Check your temperature at the same time every day before getting out of bed. Then, take notes of the results. If you have a somewhat regular cycle, the chart can help you predict when you will ovuler next.

Tracking the BBT more often can make your predictions more accurate. Often taking BBT helps to measure and keep a track of ovulation; however, BBT alone cannot predict future ovulation.

BBT is slightly lower during the follicular phase which is also known as the first half of the menstrual cycle, increases after ovulation, and remains elevated during the luteal phase that is the second half of the menstrual cycle.

Le changement de température après l'ovulation est négligeable dans lequel le BBT n'augmente que de 0,5 ° F / 0,3 ° C à 1,0 ° F / 0,6 ° C et peut facilement être affecté par des facteurs tels que la maladie, l'alcool et les changements dans le sommeil, ce changement se produit en réponse à la quantité de progestérone libérée après l'ovulation.

Why Does It Take So Long For BBT To Rise After Ovulation?

The change in Basal body temperature (BBT) depends on a number of factors, including hormone levels. During ovulation, the hormone progesterone causes a rise in temperature. It rises higher within two weeks of waiting. Then, just before your period begins, your progesterone hormone levels drop.

This generally means that your basal body temperature will also drop if you are not pregnant, in which case your temperature will continue to rise due to high progesterone levels.

When you observe the Basal body temperature charts, you are basically looking for the big picture, not the temperature rise in one place or another. Your temperature may rise and fall as your cycle continues, but you should notice a biphasic pattern after ovulation which means that the average temperature is lower before ovulation than after ovulation.

By observing at least three consecutive increases in average temperature, you will most likely know that ovulation occurred the day before the first comes out to be maximum.

Un tableau de température corporelle basale est un excellent moyen de suivre vos cycles et vos schémas d'ovulation, et peut également aider votre médecin à déterminer si l'infertilité ovulatoire est possible. Si vous craignez de ne pas ovuler, apportez votre carte BBT à votre gynécologue car lorsqu'une grossesse est détectée, la carte BBT ne peut donner que de petits indices.

Conclusion

Dans les cas liés à la BBT et à l'ovulation, il peut prendre un certain temps pour s'habituer à surveiller et à enregistrer la température et à se renseigner sur les changements dans votre corps ainsi que les autres signes que vous êtes dans un cycle incluent la sensibilité des seins, la douleur autour des ovaires, et une condition de la muqueuse cervicale.

Ainsi, de nombreuses femmes gardent une trace de cela quand elles commencent et quand elles finissent. Cependant, vous pouvez toujours consulter un médecin pour d'autres questions. Peu importe à quel point il peut être tentant de rechercher les premiers signes de grossesse et bien qu'il puisse être stressant d'attendre un test de grossesse en même temps.
