How long does ovulation last?

When a woman is in her ovulation period, her body will undergo some obvious changes, the most common of which is high body temperature. At this time, women should pay attention. If they do not want to get pregnant, they need to use contraception to avoid causing damage to their bodies. How long does the ovulation period last? This is something many women are not clear about. The following is a detailed introduction so that women can have some understanding of this type of issue.

How long does the ovulation period last?

For women with regular menstruation, the ovulation period can be calculated based on the menstrual cycle. Generally, the ovulation period is about 14 days before the next menstruation. If the woman's menstrual cycle is 28 days, her ovulation period should be around the 14th day of the menstrual cycle; if the woman's menstrual cycle is 40 days, her ovulation period should be around the 26th day of the menstrual cycle (that is, about 14 days before the next menstruation). According to the survival time of sperm and egg, conception is generally easy to achieve within about one week before and after ovulation, so this is considered to be the dangerous period for conception. Second, measuring basal body temperature can accurately grasp your ovulation period. Basal body temperature measurement refers to the oral body temperature measured after 6 to 8 hours of sleep, when you wake up without performing any activities (such as talking, eating, or getting up). The temperature records measured by date are connected into a curve, which is called the basal body temperature curve.

Because the progesterone secreted by the ovaries after ovulation can stimulate the body temperature center to increase body temperature, the basal body temperature of those who ovulate is low in the first half of the menstrual cycle, while the basal body temperature in the second half, that is, after ovulation, rises. Generally, the temperature difference between the two can reach about 0.5°C, thus showing a biphasic change with ups and downs on the basal body temperature curve. If there is no ovulation, the basal body temperature curve will be flat and unchanged and will be monophasic.

The ovulation period is usually on the day when the body temperature drops and then rises again on the curve. In some women, or during some menstrual cycles, the body temperature may not drop significantly or may not drop at all, but as long as the body temperature starts to rise, it can be considered that ovulation has occurred. Women whose body temperature changes are not obvious during ovulation can measure several more menstrual cycles so that they can understand their own ovulation patterns. In addition, factors such as cold, fever, or use of progesterone should be excluded when measuring basal body temperature.

After understanding how long the ovulation period lasts, women should pay attention to their diet and daily routine during their ovulation period. The female body is easily damaged at this time, so the diet should be reasonable and eat more foods that are good for the body. At the same time, do not stay up late. Going to bed early and getting up early is more helpful to the body.
