Nowadays, using ovulation period calculation software can calculate a woman's safe period, which is very helpful for contraception and pregnancy preparation. There are actually many methods to calculate ovulation period, but the most accurate method varies from person to person. For women with normal menstruation, the menstrual cycle calculation method is a relatively accurate approach.
Female ovulation is influenced by the endocrine hormones of the pituitary gland and ovaries, presenting periodic changes. The duration of both cycles is consistent, with one cycle per month, and ovulation occurs between two menstrual periods. The menstrual cycle of women varies in length, but the interval between ovulation and the start of the next menstrual cycle is relatively fixed, usually around 14 days.
So based on this relationship, the ovulation period can be calculated according to the menstrual cycle. The calculation method is to count from the first day of the next menstrual cycle, and subtract 14 days from the last 14 days to determine the ovulation day. The ovulation day, along with the first 5 days and the last 4 days, is called the ovulation period.
For example, if a woman's menstrual cycle is 28 days and the first day of her current menstrual cycle is on December 2nd, then her next menstrual cycle will be on December 30th (December 2nd plus 28 days). Subtracting 14 days from December 30th, then December 16th is the ovulation day. The ovulation period is from December 11th to 20th, which includes the day of ovulation, as well as the 5 days before and 4 days after ovulation. Except for the menstrual period and ovulation period, the rest of the time is a safe period.
The safety period calendar is for reference only due to significant differences in individual physical fitness. Sexual intercourse during the safe period does not require the use of any contraceptive drugs or tools.
Calculate menstrual cycle. This method is suitable for women with regular menstrual cycles. From the first day of menstruation, the last 14 ± 2 days are the ovulation period. For example, if the menstrual cycle is 28 days and the first day of this menstrual cycle is July 28th, then one of the 12th, 13th, 14th, 15th, or 16th of this month is ovulation day.
There are several methods for calculating ovulation period, including:
1. Observe cervical mucus.
In the middle of menstruation, 1-2 days before ovulation, the vagina will become increasingly moist, and the secretion will not only increase, but also be as clear and transparent as egg white. Touching with the tip of the finger can pull out long threads. The appearance of such vaginal discharge indicates that ovulation is about to occur, usually lasting for 3-5 days.
2. Feel lower abdominal pain.
During ovulation, there may be a slight pain in the lower abdomen, especially on the right or left side of the lower abdomen. Some women may experience severe pain at the moment when the egg is released from the ovary. This feeling of pain is a signal of ovulation, and this day is also ovulation day.
3. Measure basal body temperature.
The menstrual period and the week after menstruation are a continuous period of low temperature, transitioning to a high temperature period and then returning to a low temperature period, and then repeating this process in the next menstrual period. On the day when the transition from the low-temperature period to the high-temperature period becomes the dividing point, the basal body temperature will be particularly low. Centered around this day, the first 2 days and the last 3 days are ovulation days.
For women with irregular menstruation, they can wait until their period is clean and go to the hospital for B-ultrasound monitoring to know if ovulation has arrived. This approach is relatively reliable, and the test results are also relatively accurate. You can also buy ovulation test paper yourself to check if you have reached the ovulation period.
