Failure to detect a pregnancy result after four days of delayed menstruation may be due to late ovulation or lack of pregnancy.
Normally, a positive urine pregnancy test can be measured after three to five days of delayed menstruation in women who have regular periods, but pregnancy is related to the date of ovulation. If a woman ovulates late, it will cause a fertilized egg to form later, which will delay the appearance of a positive urine pregnancy test.
If a positive test is not obtained after four days of delayed menstruation, measurements can continue to be taken at different times. If you still do not get a positive result, you can go to the hospital for a blood test for human chorionic gonadotropin to determine if you are pregnant.
However, delayed menstruation is not always caused by pregnancy, but may also be caused by endocrine disorders due to emotional, dietary and environmental reasons.
If your period has been delayed for four days and you still can’t detect it, we suggest that you go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
