2. Other algorithms
In addition to ordinary algorithms, when fetal movement can be used to calculate when to get pregnant. Generally speaking, the first fetal movement is 18 weeks to 20 weeks. If it is a first maternal maternal, the fetal movement day is 20 weeks, which is the due date.I know that I got pregnant from one day.You can also calculate the time of pregnancy through the B -ultrasound, because you can check the development of the fetus through the B -ultrasound and calculate the fetal age, so that you can calculate the due date, then you know when you are pregnant.

In fact, the starting date of calculating pregnancy is simple, as long as you remember the last menstrual period.If you have forgotten even the last menstrual period, you can estimate the due date through another method.

On the contrary, if there are obvious double bands in the detection area, it means positive and indicates that pregnancy occurs.This detection has the advantages of fast, convenient, sensitive, and highly specificity, which can avoid cross -reaction caused by other glucose hormones with similar structures with HCG.However, women who have early pregnancy must remember that early pregnancy test strips can only be used as a initial screening test, and they must go to the hospital for diagnosis.
