It is easy to get pregnant when having intercourse during ovulation During a normal menstrual cycle, the ovaries usually ovulate once. The ovulated egg usually has to unite with sperm to form a fertilized egg within 24 hours, otherwise it degenerates. The ovaries ovulate and combine with sperm to form a fertilized egg. The fertilized egg begins to divide and gradually forms an embryo, which develops into a fetus and eventually a new life is born. The sperm from the male partner, which is activated in the female reproductive duct, swims and usually survives for 2-3 days, possibly longer in individual cases. Only one lucky sperm can enter the egg and unite with it to form a fertilized egg, which in turn conceives into a new life. Based on the life span of the egg, and the sperm survival time, we can speculate as follows: generally 2-3 days before the day of ovulation, on the day of ovulation, and 1 day after ovulation, intercourse has a higher chance of successful pregnancy. For those who are planning to have children or planning to have children in the near future, learn how to predict the day of ovulation to better arrange the sweet meeting of sperm and egg to conceive the crystallization of love. Several methods to predict the time of ovulation 1. Generally speaking, one egg is discharged in one menstrual cycle, 14 days before the next menstruation. If you have a 28-day menstrual cycle, you may ovulate on the 14th day of your period; if you have a 30-day cycle, you may ovulate two days later; if you have a 26-day cycle, you may ovulate two days earlier. 2.The day of ovulation can be predicted according to the change of basal body temperature. After ovulation, the basal body temperature will increase by 0.5 degree to 1 degree. Basal body temperature is the body temperature measured when you have enough sleep at night and lie in bed, quietly, when you wake up in the morning. The oral temperature is usually measured. It is more troublesome, and the increase in temperature suggests that ovulation has occurred, so it is a horse’s back. But this is a way to estimate the day of ovulation by yourself. 3. Ovulation test paper to predict the time of ovulation. This is a test paper to detect whether the level of luteinizing hormone in the urine meets the standard and estimate the ovulation date. Usually a positive result indicates that ovulation is imminent. However, sometimes it can be wrongly predicted. In this case, the follicles do not expel from the ovaries but continue to undergo some changes, aging or degeneration. This can be combined with ultrasound to confirm the diagnosis. 4. Transvaginal ultrasound monitoring This method is currently the most objective way to reflect the growth and development of follicles and the presence of ovulation. It can follow the growth of the follicles, determine whether ovulation is occurring, and also check the changes in the endometrium. It is sometimes combined with a hormonal test to better determine the quality of the follicles. For women with a 28-30 day menstrual cycle, you may have your initial monitoring on day 11-12 of your menstrual cycle, followed by the next monitoring time depending on the size of the dominant follicle. For smaller follicles, the measurement interval should be longer; for larger follicles, the measurement interval should be shorter. When the follicles reach 18-20mm in diameter, it indicates that the follicles are nearly mature and can be injected with HCG and observed 48h later to see if the follicles are expelled. If the mature follicle has disappeared or collapsed, progesterone can be given appropriately for luteal support. 14 days later, urine test or blood test can be done to determine if there is pregnancy. If the HCG is positive, suggesting the possibility of pregnancy, luteal support can be continued. Until about 15 days after HCG positive, perform vaginal ultrasonography to see if there is intrauterine pregnancy. 5. Endocrine hormone examination. Based on the hormone test results, speculate the time of ovulation, whether ovulation is occurring and estimate the quality of the follicles. The follicle growth process will produce estrogen, so the estrogen level can reflect the quality of the follicle. After ovulation, the corpus luteum produces progesterone (progesterone), and monitoring the progesterone in the blood can reflect the function of the corpus luteum. Sometimes the follicle does not ovulate and the follicle undergoes luteinization, which also produces progesterone, and the hormonal changes at this time are similar to the hormonal changes after ovulation. This method is usually combined with ultrasound to better assess the quality of the follicle and predict the presence or absence of ovulation. Each of the above methods of estimating the timing of ovulation has its own advantages and disadvantages. Sometimes it is important to combine 2-3 methods in order to determine the day of ovulation and increase the chances of conception to help everyone have a successful pregnancy.
