Being cold is a sign of implantation

After a woman becomes pregnant, the sperm and egg combine to grow and develop in the woman's body, thus giving birth to a fetus, a baby, etc. Of course, a good environment is also needed during the process of sperm and egg combination and development. So, will the embryo be afraid of cold when implanting? Today, let’s learn about it together.

Will the embryo be afraid of cold after implantation?

The embryo will feel cold when it implants. The first category is cold symptoms, such as chills, fever, constant sleepiness, fatigue and other symptoms. It is recommended to take more rest to avoid fatigue. The embryo implants on the 6th to 7th day after the combination of sperm and egg. Embryo implantation means that the embryo has already reached the uterus, but it is still small at that time and cannot be seen with B-ultrasound. The small fetal sac can only be clearly seen with B-ultrasound about 20 to 30 days after the embryo implants.

3-4 days after the embryo implants (that is, after the tenth day after ovulation), a weak positive result can be detected using a pregnancy test strip.

The feeling of sperm and egg combining with the bed:

1. Feeling nauseous and wanting to vomit. Some people begin to suffer from morning sickness in the first few weeks after pregnancy. You may feel nauseous or vomiting, and although morning sickness is also called "morning sickness," nausea and vomiting are not limited to the morning. You may feel nauseous all day and all night long.

2. The breasts become softer. If your breasts feel tender, soft, and swollen, you may be pregnant. This type of symptom may appear in the first few days after pregnancy. After your body absorbs a large amount of testosterone, this pain will disappear and your breasts will no longer feel uncomfortable.

3. Feeling tired. A lot of metabolism of luteinizing hormone (a male hormone) can make you feel exhausted. Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicions.

4. Going to the toilet frequently. After the sperm and egg combine and implant in the endometrium, they begin to secrete human gonadotropin (hCG). This will stimulate you to urinate more often, so you may pee more often than before.

5. Bleeding or muscle spasm. Eight days after ovulation and implantation, you may develop light pink or dark brown stains, and cramps may accompany these conditions. In fact, during the menstrual period, there may be some spotting and bleeding, but this is not a true menstrual period. It is the result of the fusion of sperm and egg and the implantation of the embryo in the uterine wall.

What problems may occur during embryo implantation?

Embryo implantation occurs approximately 6 days after fertilization. At this time, most pregnant women do not have very obvious reactions. A very small number of women will discharge some bright red or light pink blood, which is called implantation bleeding. Not everyone has this symptom, so it is not an obvious sign of pregnancy.

Implantation bleeding occurs about 7 days after pregnancy. If it is 7 to 10 days away from ovulation, then it can be suspected that the embryo has implanted. You can go to the hospital for examination. If it is more than 12 days away from ovulation, it may be menarche.

There will be no bleeding when the embryo implants normally. If the woman is in her ovulation period during sexual intercourse and the man has good sperm motility, pregnancy can usually be achieved within 24-48 hours. The woman will not feel anything when the embryo implants, and only a small number of people will bleed a small amount when the embryo implants due to physiological and physical problems.

Implantation bleeding is a type of abnormal uterine bleeding (dysfunctional uterine bleeding) due to imbalanced function. Because a pregnant woman has an egg that slowly grows and matures in each menstrual cycle, the body's estrogen level also slowly rises. When the mature follicle ruptures and ovulates, the body's estrogen level drops sharply, and it can no longer maintain the growth of the uterine wall, causing partial necrosis and peeling of the uterine wall, which manifests as vaginal bleeding. After ovulation, the egg quickly produces progesterone, and the lutein secretes a certain amount of estrogen and estrogens, which quickly repair the ruptured uterine wall, so the bleeding will automatically stop.

Changes in body temperature after embryo implantation: The human body temperature will decrease after the embryo implants. Implantation cooling is based on the ability to accurately measure ovulation temperature. The ovulation body temperature is to compare your own low temperature and high temperature. As long as the difference between the high and low temperature tests is more than 0.3-0.5 degrees, it is normal. According to the ovulation temperature curve, you can make some more accurate judgments. When the temperature changes from low to high, there will be an extremely low temperature. This extremely low temperature is usually your ovulation period.

When the ovulatory follicle ruptures during ovulation, estrogen levels drop dramatically, and the drop in estrogen levels can also affect body temperature. After entering the pink layer, the life of progesterone is 14 days, so the high temperature period will be maintained for about 12 days. When you find that between the 6th and 10th days after ovulation, the body temperature suddenly drops one day, and then rises significantly on the second day, this sudden low temperature is the implantation cooling.

There is also one thing to note: In general, women's body temperature is slightly higher than that of men of the same age. Women's body temperature is higher before menstruation, and it drops by about 0.2-0.3 degrees during menstruation. During ovulation, the body temperature generally drops by another 0.2 degrees, and then rises suddenly. During a woman's pregnancy (usually 3-4 weeks), her body temperature may continue to rise slightly. If the menstrual cycle has always been regular, but the menstruation did not come on time this time, and the body temperature during the ovulation period is above 37 degrees for more than three weeks, then after eliminating other fever conditions, it can be considered as early pregnancy.

It is not difficult to see that the human body temperature decreases slightly after the embryo implants. Therefore, grasping the changes in body temperature during embryo implantation can also be used as a factor in determining whether the embryo is likely to implant.
