There are also very few women who will come to menstruation once or twice after pregnancy, but the amount is small and the time is short, which is called menstrual leakage. Everyone should pay attention to the distinction. Therefore, after menstruation is postponed, it is necessary to supplement other testing methods to confirm pregnancy.
The change of basal body temperature can be used to judge pregnancy. The basal body temperature in one menstrual cycle is generally low before and then high, and will return to a low value before the next menstruation. If the basal body temperature remains high for more than 18 days, it is likely to be pregnant.
Others judge pregnancy by early pregnancy reaction. I suspect that I am pregnant after I have symptoms such as nausea, vomiting and drowsiness. This sensitivity is good and not easy to miss. But this may be gastrointestinal discomfort or a cold, and it may be a pseudo-pregnancy caused by mental stress. So if these reactions occur, we must make a diagnosis by other means.
Detection of human chorionic gonadotropin, that is, hCG detection, is the most advanced pregnancy test at present. About 6 days after fertilization, hCG enters the maternal blood and rises rapidly. Almost 1 0 day after fertilization, it can be measured from pregnant mother's serum. If the result exceeds 5, it will be considered as related to pregnancy. If it exceeds 10 and doubles every other day, the early pregnancy in uterus can be basically determined. If you are pregnant with twins or multiple births, the number may be higher. And if it is only 5 to 10, we need to consider embryonic dysplasia or ectopic pregnancy. Remind everyone that you don't need an empty stomach to take blood test for hCG.
The principle of early pregnancy test paper is to test hCG in urine. Generally, it is necessary to have the same room 14 days later, and the menstruation is delayed for more than 3 days, which has higher accuracy. If there are ribbons in both the control area and the detection area, it means that you are pregnant. The accuracy of early pregnancy test paper varies greatly. According to the time and method of detection, false negative or false positive may appear. Therefore, although this kind of detection is convenient and relatively accurate, it cannot be completely trusted. After 6 weeks of menopause, you can use B-ultrasound to detect it. If you see a pregnancy in the uterus, it means that you are pregnant, and it is intrauterine pregnancy. B-ultrasound is more expensive and troublesome, but it is generally more accurate.
I suggest: after you find that your menstruation is delayed, you should first test it with early pregnancy test paper. If it is positive, you should go to the hospital for blood test and B-ultrasound diagnosis. If it is negative, it can be tested again in two or three days. If you are really anxious, you can also go to the hospital for blood test in the same room 1 0 days or so. I wish all expectant mothers who are pregnant are so pregnant ~
