What is the average length of your menstrual cycle?

Calculate ovulation date

2-3 days before ovulation and 1-2 days after ovulation are the times when it is easy to get pregnant, because the sperm can survive in the fallopian tube for 2-3 days, and the egg can survive in the fallopian tube for 1-2 days.

Ovulation Calculator calculates the start date of your next period based on the start date of your last period and your menstrual cycle. The 14th day before the next menstruation is the ovulation day; at the same time, the 5 days before and 4 days after the ovulation day, plus the ovulation day, a total of 10 days are called the ovulation period.

female menstrual cycle

The female menstrual cycle refers to the time interval from the first day of the last menstrual period to the first day of the next menstrual period, and the calculation of the menstrual cycle is calculated from the first day of the menstrual cycle.
The menstrual cycle has four phases:
1. Menstrual period;
Menstruation usually lasts 3-7 days, during which the lining of the uterus is shed and excreted, causing bleeding.
2. Follicular phase;
The follicular phase lasts 10-14 days, during which the follicles in the ovaries begin to develop and release eggs.
3. Ovulation period;
The ovulation period is an important stage of the menstrual cycle, usually in the middle of the menstrual cycle, and the ovulation period lasts about 1-2 days. During ovulation, a mature follicle in the ovary releases a mature egg, ready to be fertilized.
4. Luteal phase;
The ovary after ovulation leaves behind a structure called the corpus luteum, which maintains hormone levels and provides support for a potentially fertilized egg. If there is no fertilization, the corpus luteum will gradually shrink and enter the next menstrual cycle.

How to calculate ovulation period

Ovulation calculation methods include calendar calculation, basal body temperature calculation, cervical mucus observation, ovulation test paper calculation and other calculation methods; the ovulation calculator we use is based on calendar calculation.
1. The calendar calculates the ovulation period;
The way the calendar calculates the ovulation period is to record the start date of the last menstrual period and the menstrual cycle to calculate the start date of the next menstrual period. Calculated from the day when the next menstruation begins, 14 days in advance is the ovulation period, also known as the ovulation day. 5 days before the ovulation day and 4 days after the ovulation day, plus the ovulation day, these 10 days are called the ovulation period. 2-3 days before ovulation and 1-2 days after ovulation are the periods when it is easy to get pregnant.
2. Basal body temperature calculation method;
When measuring body temperature, pay attention to the choice of thermometer, measurement time, continuous measurement, temperature recording, etc.; the thermometer scale needs to be accurate to 0.01 degrees; do not eat or exercise before measurement, keep your body quiet and relaxed. At the same time, the body temperature is relatively stable; you can choose to measure your body temperature when you wake up in the morning, and put your body temperature under your tongue or armpit for 5 minutes.
During ovulation, body temperature will reach the lowest point of the entire menstrual cycle on the day of ovulation; body temperature will rise immediately after ovulation, usually starting 1-2 days after ovulation, and basal body temperature will rise slightly by about 0.3 to 0.6 degrees Celsius, the actual situation varies from person to person varies.
Record the body temperature test results when you get up every morning, connect them into a coordinate map, and see the body temperature changes intuitively, so as to judge the ovulation day.
3. Observe cervical mucus;
Cervical mucus changes during ovulation; before ovulation, cervical mucus is less and thicker; during ovulation, cervical mucus is clear, smooth, and elastic, which facilitates the entry of sperm into the uterus.
4. Ovulation test paper;
The detection method of ovulation test paper is to detect the concentration of luteinizing hormone (LH) in urine. Before ovulation, LH concentrations rise sharply, usually peaking 24-48 hours before ovulation.
5. Observe whether there is discomfort or pain in the abdomen;
Some women experience mild abdominal discomfort or pain during ovulation. If this phenomenon occurs during ovulation, it can also be used as a way to observe ovulation.
6. Breast changes;
As hormone levels change, some women experience breast pain or tenderness during ovulation.
Physiologically, ovulation signs can be observed according to body temperature changes, cervical mucus changes, abdominal pain changes, breast changes, etc.

ovulation signs

1. The cervical mucus in the menstrual cycle is relatively thick, but before the ovulation period, the cervical mucus will become transparent, smooth and elastic, similar to egg white.
2. After ovulation, due to the formation of the corpus luteum and the secretion of progesterone and other hormones, the body temperature rises, 0.3-0.6 degrees Celsius.
3. Some women experience abdominal pain or discomfort during ovulation.
4. During ovulation, due to changes in hormone levels, some women may feel that their breasts become more sensitive or painful.

increase chances of pregnancy

To increase your chances of getting pregnant, you can also:
1. Couple life within 1-2 days before ovulation can increase the chance of pregnancy.
2. Quit smoking.
3. Drink less alcohol and reduce alcohol intake.
4. Regular and moderate exercise.
5. Control your weight, don't be too fat or too thin.
6. In terms of diet, choose foods rich in iron, including: beans, eggs, lentils, spinach, fortified grains, whole grains; and reduce trans fats and more monounsaturated fats; eat less animal protein, more Eat plant protein; eat more high-fiber, low-glycemic, carbohydrate-rich foods.
