Causes of a Missed Period When Pregnancy Test is Negative

Before now, there were no dependable methods of testing for pregnancy unless a woman goes to see her doctor. However, this became a thing of the past when the first at-home pregnancy test was invented in 1976.

However, there’s still a lot of unknowns about a woman’s menstrual cycle despite advancement in technology that allows a women know whether they are pregnant or not.

A woman may experience a missed or delayed period, but her pregnancy test will still indicate negative. This can make a woman very worried. Some underlying medical conditions or lifestyle factors may be responsible for this.

Here are a few reasons your period may be late or missed, even if your pregnancy test is negative.

  1. Ectopic pregnancy

In some rare cases, ectopic pregnancy can appear as negative on a pregnancy test. Seek medical attention if your pregnancy test is negative and you have these accompanying symptoms:

  • Bleeding or spotting
  • severe pain low in your abdomen or one-sided pain
  • nausea and vomiting
  • dizziness or lightheadedness
  1. Low levels of hormone

In some cases, the levels of the pregnancy hormone called human chorionic gonadotropin (Hcg) aren’t yet high enough to be detected by a home pregnancy test in early pregnancy.

A woman’s cycle can differ widely, so if you get pregnant later in your cycle, your hormone levels may not be high enough at the time of your missed period.

  1. Breastfeeding

Breastfeeding can cause some irregularities in your monthly menstrual cycle. It may even take some time before your cycle goes back to normal even after your baby arrives and your period returns.

Breastfeeding is also unpredictable month to month. As babies grow, their feedings may change. If your baby goes through a growth spurt and abruptly increases the frequency of night feedings, your cycle may be affected.

  1. Lifestyle factors

Several factors like stress, malnutrition, excess caffeine intake, sudden intense exercise, can affect your menstrual cycle.

  1. Medical conditions

Some medical conditions including polycystic ovary syndrome (PCOS) or thyroid problems, may affect a woman’s period. Some women may have very light periods, some may have very heavy periods, and some may skip periods.

Menopause typically begins around age 50. In some women, however, it can start prematurely, before the age of 40. It’s different for everyone. If you have missed your period for over 90 days and are not pregnant, consult your doctor.

  1. Medications

Taking birth control medications may cause abnormalities in your cycle. Other types of medications may lead to a missed period too. For example, blood pressure drugs or allergy tablets can throw off your cycle.


Different factors may be responsible for you getting a missed period when pregnancy test is negative. You may be dealing with an undiagnosed medical condition, such as polycystic ovary syndrome, (PCOS), or it could be a lifestyle issue, such as extreme stress. After getting a negative test result, you should wait a few days to a week before taking another test. Consult your doctor if you test negative a second time and still haven’t had your period.
