Can I take a pregnancy test if my period is three days late?

If your menstruation is regular and you have sex, then cessation of menstruation is an obvious symptom of pregnancy. However, it is not necessarily caused by pregnancy. At this time, the easiest way to find out is to use a pregnancy test strip. The test results are relatively accurate. So, can I do a pregnancy test if my period is three days late? Let’s take a look below.

It is possible to detect pregnancy if your period is three days late. Pregnancy testing is done because the level of human chorionic gonadotropin in the body increases after pregnancy, and tests are conducted based on the increase in hormone levels. Therefore, for pregnant women with regular menstruation and normal ovulation, or early ovulation, urine or blood tests can detect elevated levels of human chorionic gonadotropin about 30 days after amenorrhea. In addition, for pregnant women with irregular menstruation, delayed ovulation or delayed conception, pregnancy cannot be detected if the menstruation is three days late. Because the level of human chorionic gonadotropin has not yet increased, urine or blood tests cannot determine whether you are pregnant.

How long can I detect the pregnancy test stick after my period is delayed?

Usually, pregnancy can be detected 18 days after intercourse or if menstruation is delayed by 7-10 days. Because after the sperm and egg combine to form a fertilized egg, it takes 6-8 days for the endometrium to implant, and then 7-10 days for the HCG secreted by the placenta to enter the urine. It is scientific to test whether you are pregnant from the urine 18 days after having sex.

Fatigue, emotions, gynecological inflammation, and endocrine changes can all cause irregular menstruation. It is normal for menstruation to come one week early or late. If menstruation does not come for more than 10 days or more, it is recommended that you use an early pregnancy test or a blood HCG test to confirm the diagnosis. If pregnancy is ruled out, irregular menstruation is considered and an endocrine test is needed to determine the cause.

If you normally have a normal menstrual cycle but have symptoms of amenorrhea this time, it is recommended that you use an early pregnancy test to check whether you are pregnant about 10 days after your period is delayed. Even if you are pregnant at this time, the hormone levels in your body have not increased significantly and cannot be detected due to the short period of time.

It is normal for your period to come a week early or late. First, you need to confirm whether you are pregnant. Mental delays also need to be considered as mental factors. Work pressure, environmental changes, and gynecological diseases may all lead to delayed menstruation. There are many reasons for delayed menstruation. One is functional, such as endocrine dysfunction can cause delayed menstruation; the other is organic, such as pelvic inflammatory disease, endometritis, and endometriosis, which can also cause delayed menstruation.
