Judging from leucorrhea whether sperm and egg are combined

Leucorrhea is a liquid discharged by women during menstruation. It is usually transparent, but it may contain blood during menstruation. This is a normal physiological phenomenon. It is impossible to tell whether fertilization has occurred from the leucorrhea because the combination of sperm and egg will not affect the normal leucorrhea. However, the secretion of estrogen in women's bodies will increase, which can be determined by checking the hcg value in the blood.

As far as current medicine is concerned, it is impossible to tell whether the sperm and egg have combined from the leucorrhea. After the sperm and egg combine, the estrogen and progesterone levels in the body will indeed be at a high level, but the estrogen and progesterone levels in the body are also at a high level before menstruation. Therefore, as long as the levels of estrogen and progesterone are high, they will stimulate the shedding of cervical mucus cells and vaginal wall cells, resulting in the appearance of yogurt-like curdled vaginal discharge. Therefore, it is impossible to determine whether the sperm and egg are combined simply from the vaginal discharge, and only blood tests of hCG and urine pregnancy tests can determine it.

What are the symptoms after sperm and egg combination

1. Implantation cooling: After having sex, pregnant mothers may find that their body temperature suddenly drops one day in the 6 to 10 days after ovulation, and returns to normal the next day. This drop in temperature is implantation cooling, which is a signal that the fertilized egg has successfully implanted.

2. Breast swelling and pain, nipple tenderness: After the fertilized egg implants, the breasts will feel soft and swollen, and the nipples will feel tender from time to time. These changes are telling you that you may be pregnant! Once you adapt to the changes in your body's hormones, this discomfort will be relieved and subside.

3. The feeling of having a cold: Although you are not sick, your body feels tired and your appetite has decreased. This is because the large amount of progesterone secreted after conception will make women feel tired. You can determine whether you are pregnant based on other reactions of your body.

4. Implantation bleeding: Some women will experience implantation bleeding 6 days after fertilization, with red or pink blood flowing out, but not every woman will experience this.

How long does the egg survive?

The life span of an egg is much shorter than that of a sperm, and the survival time of an egg is 12-24 hours. If the egg that enters the fallopian tube meets the sperm within 24 hours, the sperm and egg can combine and fertilize. If the sperm and egg lose the opportunity to meet at this stage, the egg will lose the ability to be fertilized and die. Therefore, pregnancy is only possible if you have sex during the middle of your period, that is, within 1-2 days before or after ovulation.
