A weakly positive ovulation test result before a woman’s period does not indicate pregnancy. Ovulation tests are used to detect ovulation in women, and a positive test result generally indicates that a woman is ovulating. A weak positive result on an ovulation test before menstruation generally indicates that the ovulation period is almost over, which has no direct relationship to whether or not you are pregnant. If a woman does not use contraception during intercourse during ovulation, she may become pregnant. But even if you are pregnant, you can’t detect it with ovulation test paper before your period. A more convenient and effective way to check for pregnancy is to use morning-after test strips to test the morning urine after the period has been delayed for a period of time, and if the result is positive, it usually means that you are pregnant.
