Will an Ovulation Test be Positive if Pregnant?

Should you use an ovulation test as a pregnancy test?

Simply put, ovulation tests identify the increase in luteinizing hormone (LH) that occurs just prior to ovulation. Just prior to ovulation, LH surges and actually signals the ovaries to release an egg. We use an ovulation test to track the rise and progression of LH levels in an effort to foretell the day of ovulation so you can time sexual activity with your peak fertile days to conceive more quickly.

However, after ovulation, luteinizing hormone levels drop to low levels, where they will stay for the remainder of your cycle or the duration of your pregnancy. After ovulation occurs, LH really serves no purpose while you are pregnant other than to trigger ovulation and aid in the development of the corpus luteum that is left over.

Let me be very clear…. Ovulation tests are much less sensitive and reliable at detecting hCG, so I strongly advise using hCG pregnancy tests to find out if you are pregnant.

How does a positive pregnancy test differ from a positive ovulation test?

Ovulation tests will detect both hCG and LH as positive results because they are less sensitive than early pregnancy tests. A home pregnancy test that looks for hCG detects LH levels at 10 mIU/mL while ovulation tests typically detect levels around 25mIU/mL. As a result, an ovulation test is unlikely to detect pregnancy as quickly as a pregnancy test would.

Because an hCG pregnancy test is more sensitive, they will only respond to significant levels of hCG. This explains how a pregnant woman can have a negative pregnancy test one day, a light positive result the next, and then a dark positive result a few days later.

The only way to determine whether you are pregnant when you see a positive result on your ovulation test as your period approaches is to take a pregnancy test. In contrast to how hCG will appear on an ovulation test, the LH will not be positive on a pregnancy test.

Causes of a Negative Pregnancy Test

In the absence of pregnancy, there are a number of reasons why a negative pregnancy test with a missed period could occur.

Determine whether you are successfully ovulating each month when trying to conceive because ovulatory dysfunction or anovulation may be the cause of your missed period and may have an impact on your ability to conceive.

There are many causes for ovulatory dysfunction or anovulation. Just a handful of these causes include:

  • Polycystic ovary syndrome (PCOS)
  • Thyroid dysfunction
  • Being over/underweight
  • Stress
  • The condition known as primary ovarian insufficiency (POI) may affect some women. The symptoms of POI are comparable to menopausal symptoms. Premature onset of menopause is accompanied by hot flashes, dry vaginal skin, and an absence of menstruation as the ovarian follicle count declines.

    Although the typical menstrual cycle lasts 28 days, we frequently forget to record the first day of our cycle. Additionally, the length of cycles can occasionally change from month to month. To accurately predict when you are most likely to become pregnant, you can chart your basal body temperature or use ovulation prediction kits (OPKs).

    Second, there are a few causes for a negative pregnancy test when you are actually pregnant. Some reasons for this may include:

    I missed my period, but have negative pregnancy tests and positive ovulation tests. Why?
