How to determine if you are pregnant?
You are likely to be pregnant when the following symptoms appear:
1 Menstruation stops. If the husband and wife had sex before and after ovulation, and did not take contraceptive measures, the menstrual cycle was normal at ordinary times, and menopause symptoms suddenly appeared for more than 5 days, it was possible to get pregnant.
2, nausea and vomiting, from about the fifth week of pregnancy, many pregnant women will have morning sickness. Especially in the morning and evening, nausea will occur, and vomiting will occur without any reason. At present, the cause of morning sickness is not exact, but the data show that it may be related to human chorionic gonadotropin (HCG). At the beginning of pregnancy, the content of human chorionic gonadotropin (HCG) began to rise. The higher the level of this hormone, the easier it is to feel sick.
3, frequent urination, you may think that the sign of frequent urination will not come so early, it should appear when the fetus can squeeze into the bladder, but in fact this sign may appear in the early stage of pregnancy. Frequent urination in the early pregnancy is mainly caused by the change of hormone secretion in the body. Not only will the swollen uterus put pressure on the bladder, but the increase of blood flow will also put pressure on the kidneys, leading to an increase in urine.
In fact, the pregnancy test paper can be used on the day when menstruation expires, or it can be tested on the 7- 10 day after sexual intercourse, urine can be collected, and the test paper can be inserted, and the results can be observed within 5 minutes. The whole detection process is convenient, fast and accurate. If the test result is positive, ribbons appear at the upper and lower ends of the test strip, indicating pregnancy. If it is negative, only a purple-red ribbon appears at the upper end of the test strip and a colorless band appears at the lower end, indicating that it is not pregnant.
Key items of prenatal examination in the first trimester of pregnancy
During the early pregnancy check-up, pregnant women need to establish a pregnancy care manual, determine the gestational age, calculate the expected date of delivery, and evaluate the high-risk factors during pregnancy. The items that need to be done in the prenatal examination include blood pressure, body mass index, fetal heart rate, blood routine, urine routine, blood type (ABO and Rh), fasting blood glucose, liver function and renal function, hepatitis B virus surface antigen, Treponema pallidum, HIV screening and electrocardiogram.
People who have not had premarital and pregnancy tests before should be screened for thalassemia, and those who have pets at home should be screened for parasites. Experts remind: The first check-up is relatively the most, which is also to comprehensively check the health of expectant mothers. Take the prospective father with you for examination, and learn about the health of you and his immediate family members.
Interpretation of key items of prenatal examination in early pregnancy;
1, fetal neck transparent layer thickness detection-fetal malformation screening (NT): It is carried out at 1 1- 14 weeks of pregnancy, which refers to the accumulation of fluid in the subcutaneous tissue at the back of the fetal neck. In recent 10 years, it was found that the thickness of NT increased, and the possibility of fetal abnormality increased. When the measured value is less than 2.5mm, it is judged as normal.
2, rubella virus antibody: rubella not only infects pregnant women, but also causes vertical infection through placenta and genitals, resulting in miscarriage, intrauterine growth disorder, and congenital malformations such as congenital cataract, deafness and heart disease. Detection of rubella virus-specific antibody IgM in pregnant women's serum is helpful to predict pregnancy outcome and reduce the incidence of congenital rubella syndrome in children.
3. Human immunodeficiency virus: AIDS, also known as acquired immunodeficiency syndrome, is a sexually transmitted disease caused by human immunodeficiency virus (HIV). At present, there are more and more HIV carriers or AIDS patients in China, and the proportion of women infected is also increasing. 90% of infants and children infected with HIV are caused by mother-to-child transmission, so it is very important to screen HIV.
