How many days can I use test paper to check early pregnancy

Pregnancy test can be used to detect pregnancy after 7-10 days of menopause.

After pregnancy, the level of human chorionic gonadotropin (HCG) in a woman's body will gradually increase. Pregnancy test is to determine whether pregnancy by detecting HCG in urine. Usually after a period of menopause, HCG levels reach a certain level, can be accurately detected by the test paper. Although theoretically it may be detected soon after menopause, but to improve accuracy, it is recommended to test after 7-10 days of menopause.

If the test paper shows two red lines, usually pregnant; if only one red line, it means not pregnant. However, it should be noted that in some cases, false positive or false negative results may occur, such as expired test paper, urine contamination, etc.
