Because of the different types of test strips used by women, the meaning of one deep and one shallow test will be very different, and it will be directly related to the time of testing. If a woman uses an ovulation test after her period is cleared and a deep and shallow test appears, it is mostly considered that the LH hormone in her body has started to rise and she is about to reach the ovulation stage. For women who use the early pregnancy test, one deep and one shallow test represents a weak positive early pregnancy test, most of them are considered to be the manifestation caused by pregnancy, only because the testing time is relatively early and the rise of HCG in urine is not particularly obvious, only then a weak positive test appears instead of a strong positive test.
