For women with regular menstrual cycles, pregnancy may be detected by detecting human chorionic gonadotropin (HCG) in urine by early pregnancy test paper when menstruation is delayed by one week. Because after pregnancy, HCG levels in the body will gradually increase and can be detected after reaching a certain concentration. However, there may be certain errors in early pregnancy test paper detection, such as improper operation, test paper quality problems, etc. Some women may be pregnant late, and HCG levels in the body are relatively low, resulting in inaccurate test results and false negatives.
