Regular vacation refers to menstruation. When menstruation is delayed, a weak positive ovulation does not indicate pregnancy and should be detected by a pregnancy test. Delayed menstruation is one of the signs of pregnancy, but this method is suitable for women who have regular menstrual periods and does not have a clear meaning for women who have irregular periods. If your period is delayed and you want to determine if you are pregnant, you should use a pregnancy test or go to the hospital for a blood HCG test to determine if you are pregnant. If the ovulation test is weakly positive, it means that the ovaries are about to ovulate, and if there is a need to prepare for pregnancy, you can have sex at this time to improve the chances of conception. If there is a delay in menstruation accompanied by a weak positive ovulation test, it is recommended to consult a doctor, under the guidance of the doctor to determine whether there is a possibility of pregnancy, and if there is a need to prepare for pregnancy, it is recommended to choose a scientific method under the guidance of the doctor, to improve the chances of conception.
