Is it possible to measure the depth and depth of your period?

Women in the near menstrual period, will not use the early pregnancy test paper to detect a deep and shallow performance. Unless the woman is pregnant, this time will show a deep and shallow weak positive performance of the early pregnancy test paper. In fact, because the female pregnancy time is relatively short, the hcg hormone level in the urine is still relatively low, so the early pregnancy test paper will not show a strong positive phenomenon, but show a deep and shallow weak positive performance. For women who are not pregnant, the test will only show negative results near menstruation, because there will be no increase in hcg hormone levels in the woman's body at this time, so there will be no weak positive performance of the test.
