Can pregnancy be detected in 24 hours?

Many people believe that after a man and a woman have sex, if there is a fertilized egg, pregnancy can be detected quickly. Some people even think that it can be detected within 24 hours. However, our medical technology is not so advanced. The probability of detecting pregnancy within 24 hours is very small. It cannot be detected by ordinary methods. So can pregnancy be detected within 24 hours?

Generally speaking, you can use products such as early pregnancy test strips or pregnancy test sticks to get the results as early as 7 days after intercourse. However, the accuracy at this time is not high enough. Normally, it takes 9 days after fertilization to ensure accuracy. Because pregnancy tests are generally determined by detecting the HCG concentration in the blood or urine, that is, the concentration of human chorionic gonadotropin, but the change in the HCG concentration in the blood and urine after pregnancy takes a process, so the longer the time after sexual intercourse, the more accurate the test. In addition, there are certain deviations in self-testing pregnancy using early pregnancy test strips or pregnancy test sticks. If you want to further confirm the diagnosis, you need to go to the hospital for testing.

The best time to take a pregnancy test varies depending on the pregnancy test method chosen.

1. Early pregnancy test detection time

If you use an early pregnancy test to detect pregnancy, you can choose to test 3 to 5 days after your period is delayed. After the test, if two red bars appear on the test paper, it means you are pregnant, otherwise it means you are not pregnant.

2. Ultrasound examination time

If you want to check whether you are pregnant through B-ultrasound, you can go to the hospital for an ultrasound examination seven days after your period is delayed. Generally speaking, the accuracy of B-ultrasound examination results is still very high.

3.Basal body temperature test time

The basal body temperature test method is to test your basal body temperature every day after your period is delayed for at least seven days. If the basal body temperature remains at a high level for several consecutive days, you are likely pregnant.

4. Blood HCG detection time

Couples can go to the hospital for this test about 10 days after sexual intercourse to determine whether they are pregnant.

Main symptoms of early pregnancy

After conception, a series of special symptoms will appear in the female body. These typical symptoms can also help determine whether the woman is pregnant to a certain extent.

1. Stopping of menstruation

Generally speaking, it is normal for menstruation to be delayed by about seven days, but if it is delayed for more than ten days, you should check whether you are pregnant. Of course, sometimes excessive mental stress and some gynecological inflammation may cause delayed menstruation. Therefore, when your period is delayed for more than 10 days, you can go to the hospital for further confirmation.

2. Gagging

Chest tightness and nausea are typical symptoms of pregnancy, and the symptom appears relatively early. Generally speaking, after six months of pregnancy, as the body gradually adapts to the pregnancy, the symptom will gradually be relieved. In addition, different people experience different symptoms of morning sickness. Some pregnant women may feel like vomiting all day long, while others may feel like vomiting only at certain times of the day, such as when getting up early or at night.

3. Frequent urination

Frequent urination is another typical symptom of pregnancy and a natural phenomenon of pregnancy. Expectant mothers do not need to worry too much. Generally, after 12 weeks of pregnancy, as the uterus gradually expands beyond the pelvic cavity, this symptom will naturally be relieved.

4. Changes in basal body temperature

The body temperature of a normal woman will fluctuate after pregnancy. The basal body temperature of a normal woman presents a two-way curve, that is, the body temperature will change before and after ovulation. The body temperature of a woman will be relatively high during ovulation. If the menstruation is delayed, and the basal body temperature does not drop after rising, and lasts for more than half a month, it is very likely that she is pregnant.
