How many days can you know if you are pregnant?

Pregnancy can be detected faster, around 7 to 15 days after intercourse. Women of childbearing age with a history of amenorrhea and sexual intercourse should be suspected of being pregnant if their menstrual period is overdue for 10 days or more. Amenorrhea may be the first and most important symptom of pregnancy. But please note that amenorrhea does not necessarily mean pregnancy. Amenorrhea is the most obvious symptom. If you have sex without any contraceptive method and your period has not come on time for 2 weeks, and you still haven't had your period for more than 5-7 days, you should consider the possibility of pregnancy.

Nausea and retching: Nausea and retching are the most common signs of pregnancy. If you're like most women, morning sickness won't start until about one month into your pregnancy. A very few lucky women do not experience morning sickness throughout their pregnancy.

Breast enlargement and sensitivity: This swelling and pain is very similar to what you feel before your period, just more obvious. These pregnancy symptoms will improve significantly after the third month of your pregnancy, and your body will have adapted to the changes in male hormones during pregnancy by then.

Some women get pregnant after one month of preparation, while some women have not gotten pregnant even after a year of preparation. This has a lot to do with their physical fitness. If pregnancy has not been successful after one year, it is recommended that both parties go to the hospital for a comprehensive physical examination. If there is a problem, they can start the pregnancy preparation period after treatment. The above is a detailed introduction on how soon pregnancy can be detected. I hope everyone can raise a cute baby.

Application scope of abdominal B-ultrasound

1. Gynecological examination - check the size of the ovaries, whether there are cysts, actual masses, etc., and also observe whether there are uterine fibroids, adenomyosis, uterine endometriosis, and uterine intrauterine polyps.

Note: Ultrasound cannot confirm atypical hyperplasia of the uterine wall or endometrial cancer, which requires diagnostic curettage or endometrial biopsy.

2. Pregnancy check-up

Early pregnancy: It can be used as a basis for diagnosis in the early stages of pregnancy. B-ultrasound examination is an important step in diagnosing pregnancy. For those who are uncertain about the start date of their last menstrual period, B-ultrasound measurement is a more accurate method. The size of the gestational sac can be calculated based on the results of B-ultrasound examination, and the gestational age and delivery date can be calculated based on the length from the fetal head to the buttocks. In addition, it can also be used to understand whether there is a fetal heartbeat and yolk sac, so as to deal with any growth and development abnormalities of the test tube embryo in time.

Mid-pregnancy: B-ultrasound can be used to screen for fetal abnormalities. B-ultrasound can help doctors to promptly diagnose fetal malformations, including surface malformations and visceral malformations. For example, malformations such as congenital heart disease, cleft lip and palate, hydrops fetus, congenital fingers (toes) and external auditory canal can be detected. In addition, the exact position of the fetus in the uterus can also be determined.

Late pregnancy: The ultrasound results at this stage are mainly used to assess the size of the fetus, to observe the amount of amniotic fluid and the function of the placenta, and to see if the fetus has the umbilical cord around the neck. If there is oligohydramnios, placental calcification, or the umbilical cord around the fetus's neck, it is necessary to consider whether to get pregnant again in combination with clinical medicine.

3. Used to check the uterine recovery status after artificial abortion, medical abortion, induced labor and postpartum.

4. Observe the uterine development and endometrial thickness in patients with amenorrhea, menstrual disorders or multifunctional abnormal uterine bleeding.

5. Patients with uterine fibroids and ovarian cysts should have regular follow-up visits.

6. Evaluate reproductive function, observe uterine development and ovulation, and accurately measure the thickness of the uterus. Nowadays, many single and childless women, out of curiosity, use B-ultrasound to evaluate their own reproductive function.

7. Confirmed congenital hypoplasia of the uterus, ovaries or uterus, infantile uterus or deformed uterus, etc.
