A weakly positive ovulation test on the eighth day after ovulation that never deepens is not a way to tell if you are pregnant.
Ovulation test strips are used to determine whether ovulation has occurred by testing for luteinizing hormone (LH) in a woman’s urine. Before ovulation, the LH in a woman’s body rises significantly, the ovulation test paper appears positive and the color of the indicator mark is the darkest; after ovulation, the LH gradually decreases, and the color of the indicator mark on the ovulation test paper will gradually become lighter, indicating that ovulation has occurred.
A weakly positive ovulation test on the eighth day after ovulation may indicate that LH is still at the level that can be detected by ovulation tests, but you can’t rely on ovulation tests to detect pregnancy.
To detect pregnancy, you should use urine early pregnancy test paper to detect human chorionic gonadotropin (HCG) in the urine, or go to the hospital for blood HCG, gynecological ultrasound and other tests, so that the professional doctor can clarify whether you are pregnant.
