Rare Causes Of Test Malfunction
A rare, counterintuitive cause for a false negative is that you are too far along in your pregnancy. For example, if your period is weeks to months late, a pregnancy test might come up negative. This is called the variant hook effect.
Another unusual but possible reason for a false negative is that youre expecting triplets or even twins. In this case, a false negative pregnancy test can be caused by what is known as the high dose hook effect. Ironically, unusually high levels of hCG can cause a pregnancy test to give a false negative result.
A very rare cause of a false negative pregnancy test is when the hCG hormone in your body does not react with the anti-hCG chemicals in the test. In this case, you might need to wait a few more days before you can get a positive result or need to have a blood test.
You might ultimately need to have a serum pregnancy blood test or ultrasound to confirm pregnancy.
If you still havent gotten your period after a few more days, try the test again. If subsequent tests continue to show a negative pregnancy test result, youll want to talk to your healthcare provider about further testing.

How To Induce Your Period
Whether or not you can jump start your period or encourage it to happen depends on the root cause of the delay. In the long-term, Dr. Speichinger says that addressing some of the issues that can cause late or missed periods can help get your cycle back on track. Reducing your stress levels, getting adequate rest, cutting back on excessive exercise if youre an athlete, and normalizing your weight can reset your cycle if those things have caused the disruption in the first place.
There are also medication options that may be available to you, especially if your late period is because of a hormone imbalance. Typically, we can start with a progesterone challenge to a withdrawal period, Dr. Speichinger explains.
A progesterone challenge test involves taking progesterone orally for about 10 days, then stopping the progesterone to see if withdrawal bleeding occurs. If it does, there may be an issue with ovulation if it doesnt, the problem may be related to estrogen levels. Dr. Speichinger notes that sometimes there is a second step to the progesterone challenge, where estrogen is given first and followed by progesterone, to cause the withdrawal period.
This test can tell your womens health provider a lot about your hormonal levels, as well as the health of the lining of your uterus. It can make the next steps clearer for you and your provider as you look for the source of your late or missed periods.

How Do Urine Pregnancy Tests Work
Pregnancy tests look for the pregnancy hormone hCG, which increases as a pregnancy progresses. The normal range for hCG levels in pregnant people can vary widely. Its possible that your levels arent yet high enough to be detected .
An early pregnancy test might pick up very low amounts of hCG. However, its possible that you dont have enough circulating hCG to get a positive result even on a sensitive test.
This doesnt mean anything is wrong. How much hCG you have isnt important rather, its how quickly your levels double and increase .
Another common reason for getting a false negative is not having enough hCG in the urine you test. In early pregnancy, you can dilute the hormone concentration in your urine if you drink a lot of water before testing.
This is more likely to happen in very early pregnancy when you take the test later in the day. The hCG concentration is higher when youve held your urine for a while, which is why its recommended that you take a pregnancy test in the morning.
