You are too young, don't study hard, be a useful person to the country in the future, and engage in relationships at an early age! It's so disappointing. Generally, the college entrance examination is a routine examination, not an hCG pregnancy test, which is too expensive for the whole school. It's too expensive to check if you are pregnant. Of course, you can't find out if you are pregnant: 1. Usually, HCG (quantity check, also called B-hCG) should be checked by blood on the first 1 1 day after menstruation expires. If you are pregnant, you will. 2. As for urine hCG, it takes 12- 14 days to have a positive reaction. (B-hCG) Two obvious red lines are considered pregnant. (The red line is the test line T = test), and the other line C(C = control) is the control line. So why check urine hCG? If pregnant, there will be embryos and placenta, which will produce hCG (human chorionic gonadotropin). HCG circulates in pregnant women's blood and then appears in blood and urine. Urine hCG is the principle of urine quality inspection (using test paper), which is to check whether there is hCG in urine. If the early pregnancy test paper is weakly positive, it just tells you that you may be pregnant. If you are anxious to know, you'd better go to the hospital for a blood test of hCG or B-ultrasound, so that you can know clearly whether you are pregnant or not. HCG below 5mu/ml is a negative reaction, not pregnancy, and any amount over 25mu/ml is a positive reaction, but if pregnant, the amount of hCG in the blood of 85% pregnant women will double every two or three days. If hCG does not increase at this rate, it means that pregnancy has failed. You only need to do one thing, that is, go to the gynecology department of the hospital to have an hCG blood test, so that you can know clearly whether you are pregnant or not. More accurate and reliable than urine test. HCG below 5mu/ml is a negative reaction, not pregnancy. Anything over 25mIU/ml is a positive reaction, especially pregnancy.
