The two follicles are the same size. Every month, women will only have one mature egg, which is generally more than 20mm, but there are individual differences. Some people will ovulate when the follicle grows to 15mm, while others will ovulate when the follicle grows to 25 mm. For individual cases, it is enough to have a regular B-ultrasound examination. Usually, mature follicles will be discharged within one or two days, and the discharged follicles can generally live for two days. Generally, the development of follicles to ovulation is about 14 days before menstruation, and both ovaries are alternately discharged, but they can also be discharged continuously. In fact, there are many primordial follicles in the cortex of the ovary, and the number of follicles is fixed at birth.
1, do more exercise. The size and development quality of follicles are directly related to health. Do more sports, such as mountain climbing, running, aerobics, swimming, etc. You can choose exercise according to your preferences and physical condition. In addition, the air pollution is serious now, so try to avoid outdoor sports in foggy days.
2. Keep a good mood. Normal pregnancy is a natural process. Don't be too impatient, do B-ultrasound frequently, or artificially take medicine to promote ovulation and force ovulation, which is equivalent to pulling out the seedlings and encouraging them. Often do B-ultrasound examination, although there are no side effects, but before the examination, you need to hold your urine. There are many patients in the hospital, and holding urine for a long time is easy to make people feel irritable, which will affect the quality of follicles for a long time.
3. Develop reasonable eating habits. Meal time should be regular, such as breakfast should be finished before eight o'clock and dinner should not exceed eight o'clock. Don't overeat. Eat some mild and nourishing food, and avoid cold and spicy food. Especially now that summer is coming, we should avoid eating and eat less cold drinks, ice cream and barbecue. Remember not to smoke or drink.
Under normal circumstances, women of childbearing age only have 1 follicle mature every month, while individuals will have 2 follicles mature and ovulate 2 eggs at the same time, and most of them will have 1 egg. If there are two follicles, the large follicle is the dominant follicle. Usually, when it reaches 20x20mm, the egg will be expelled, but the small follicle will not ovulate again, and there will be automatic follicular atresia. If two follicles are the same size, they may ovulate at the same time. After the egg is discharged, it will die naturally if it is not fertilized within 24 hours.
If ovulation is delayed, the expected date of delivery really needs to be delayed accordingly. Some women have irregular menstruation, which will lead to delayed ovulation and late pregnancy. Therefore, when doing B-ultrasound in early pregnancy, it will be suggested that the fetal size does not match the menopause time, and the gestational sac will be shorter than the menopause time. In this case, it is necessary to recalculate the expected date of delivery according to the size of the gestational sac. In addition, some women can't remember their menstruation clearly, and they can also determine the expected date of delivery by doing B-ultrasound. Women with normal menstruation will also have delayed ovulation, because ovulation is affected by many factors, so as long as the fetal size and month are different during pregnancy, it is recommended to recalculate the expected date of delivery.
If women's menstruation is delayed, the ovulation period will be delayed accordingly, but this is only relative, not absolute. Under normal circumstances, if the menstruation is irregular, the ovulation period will be affected to some extent and will become irregular. Will be delayed with the advance and advance of menstruation and the delay of menstruation. The expected date of delivery is calculated according to menstruation. If menstruation is delayed, the expected date of delivery will also be delayed. But to be accurate, it is safest to go to the hospital to listen to the doctor's advice.
Generally, the pregnancy period is calculated as 280 days, and the expected date of delivery is calculated from the date of the last warning to 280 days. It used to be calculated on a monthly basis. A menstrual period is 28 days, that is, a month is calculated as 28 days, and the expected date of delivery is 10 month. But now most of them are calculated in weeks, and the expected date of delivery is in the 40th week.
Normal delivery period, that is, full-term delivery period, refers to the first three weeks or the last two weeks of the expected date of delivery, which is usually called full-term. If you give birth at 24 -36 weeks of pregnancy, it is considered premature. If the delivery is later than the normal delivery period, that is, at or after the 42nd week, it is called overdue delivery or overdue delivery.
