A pregnancy test with two bars mostly means implantation, i.e. pregnancy, but it cannot be used to diagnose intrauterine pregnancy. Under normal circumstances, it takes 7-10 days from the time the egg is discharged, to the time it unites with sperm to form a fertilized egg, and then to the time the fertilized egg enters the uterine cavity and lays. After the fertilized egg has been laid, it will secrete HCG, which will enter the maternal blood circulation. A blood test at this stage to check the HCG level in the blood can detect pregnancy at the earliest. As the pregnancy progresses, HCG levels can trend upward and can be detected in the urine as well. A urine pregnancy test can usually be performed around 35 days after menopause through a pregnancy test, and the use of morning urine can improve the accuracy of the test results. If a red reaction line, commonly known as two bars, appears at the location of both the test and control lines, the HCG in the urine has reached the pregnancy level and represents pregnancy. The results of the urine test are for reference only, because in addition to normal pregnancy, positive results can also occur for teratoma, gravidity, incomplete miscarriage, etc. For a definite diagnosis, prompt medical attention is needed to draw blood to check the HCG level and to perform ultrasound to determine whether the gestational sac is lodged in the uterine cavity to rule out ectopic pregnancy, etc. After pregnancy is confirmed, you should pay attention to rest, avoid fatigue, maintain a balanced diet with light food as the mainstay of your daily routine, and also pay attention to the supplementation of high quality protein.
