Initial symptoms: this is discovered by women themselves by feeling or according to their own physiological conditions.

1. Menstrual cessation: This is the most common sign of pregnancy. As long as a woman of childbearing age has normal menstruation and exceeds normal menstruation for two weeks after sexual intercourse, it is possible to get pregnant. But it's not that your period is not coming or you're pregnant. There are many reasons why menstruation does not come. It may be due to poor ovarian function, abnormal hormone secretion, busy work and nervous exams. These will all cause the phenomenon of late menstruation. So it's best to be diagnosed by a doctor, which is the safest.

2. The breast has tingling, swelling and itching: The breast has tingling, swelling and itching, which is a physiological phenomenon in the early pregnancy. In addition, there will be changes such as dark areola color, obvious inferior mammary vein and obvious nipple protrusion.

3. Often feel nauseous and vomiting: Almost many pregnant women in the early pregnancy often feel nauseous and vomiting, especially at the beginning of the day. These symptoms vary from person to person. Some people's symptoms are quite mild, while others are very serious. Unless you are seriously ill, vomiting and need to see a doctor, these are normal phenomena in the early pregnancy.

4. Skin color change: skin pigmentation or stretch marks on the abdominal wall, especially in the third trimester.

5. Discoloration of vaginal mucosa: At the beginning of pregnancy, the vaginal mucosa may appear darker due to congestion, which is judged by the doctor.

6. It is easy to get tired: it is easy to get tired in the early pregnancy and often wants to sleep.

7. Frequent urination: In the third month of pregnancy, because the bladder is compressed by the expanded uterus, the bladder volume becomes smaller and frequent urination occurs.

Clinical symptoms: This refers to the changes discovered by doctors and themselves.

1. Abdominal enlargement: In the third month of pregnancy, the abdomen has obviously enlarged, but before the pregnancy is confirmed, it may be because there is a tumor in the abdomen or the weight has risen sharply, which makes the abdomen enlarged. So at this time, you must do further examination to determine whether you are pregnant.

2. You can feel the shape of the fetus: this is also one of the more reliable pregnancy symptoms, usually around the fourth or fifth month, and you can also feel fetal movement. But remember not to treat abdominal tumors as the shape of a fetus, or you need to ask a doctor to make a more correct judgment.

The cervix becomes soft and the uterus becomes round: this must be known through the doctor's internal diagnosis. Occasionally, the uterus will contract painlessly, and you can feel the change by touching your abdomen.

3. Pregnancy test: If menstruation has been late for more than two weeks, you can do a urine hCG test. As long as it takes five minutes, you can check whether you are pregnant. However, the accuracy of 100% is not defined as intrauterine pregnancy, because besides human chorionic gonadotropin (hCG), there are others in the urine of pregnant women, such as ectopic pregnancy, hydatidiform mole and choriocarcinoma. There will be a positive reaction when doing this experiment, so the hCG test in urine can only be used as a reference for doctors to judge whether they are pregnant or not.

Determine the phenomena of pregnancy: these phenomena are clear messages from the fetus in the abdomen, which will gradually become obvious around the sixth week of pregnancy.

1. Ultrasound can see the outline of the fetus: however, the position of pregnancy and the heartbeat of the fetus can be determined after six weeks of pregnancy, and various structures of the fetus can be observed through ultrasound after twelve weeks of pregnancy.

2. Hear the fetal heartbeat: you can clearly hear it with the fetal heart detector at the twelfth week of pregnancy, and you can hear the fetal heartbeat with the fetal heart microphone at the eighteenth to twentieth week, with a frequency of about 120~ 160 times per minute.

3. Feel fetal movement: In the fifth month of pregnancy, you will feel fetal movement in the uterus, which is called fetal movement.
