What Is A Pregnancy Test
A pregnancy test is a way to determine if youre pregnant. If your pregnancy test is positive, it means youre pregnant. If the test is negative, it means you arent pregnant. Pregnancy tests work by detecting human chorionic gonadotropin , a hormone your body makes when youre pregnant.
From the very beginning of pregnancy, your body starts to go through changes to support the cells that will develop into your baby. One thing that happens very quickly is the production of HCG. If youre pregnant, your body starts to produce more HCG. Your HCG levels start to build up once the fertilized egg implants in your uterus about six to 10 days after conception.
There are two main types of pregnancy tests urine tests and blood tests. Often, youll take a urine test at home with a home pregnancy test. This type of test is available over the counter and in a variety of price ranges. Blood tests to check for pregnancy happen in your healthcare providers office and involve giving a sample of your blood. The other way to confirm a pregnancy is by using an ultrasound. Your provider performs an ultrasound in their office.
What hormone levels are checked for a pregnancy test?
Pregnancy tests look for an elevated amount of HCG. Levels of HCG rise quickly doubling every few days in the first weeks of pregnancy. The placenta produces HCG. Only pregnant people have a placenta, which develops shortly after a fertilized egg attaches to your uterine wall.
What About Early Pregnancy Tests
Early pregnancy test manufacturers market to your desire to get answers as early as possible. It is not hard to see the advertising on the box and read the claims of 99% accuracy along with the ability to detect pregnancy six days before your missed period.
But let us take a closer look, so you do not test too early for pregnancy. The first thing to consider is that the percentage provided on the front of the package is only accurate when you take the test on the day of your expected period and in a laboratory setting by professionals. The same goes for the the instructions printed inside the pregnancy test kit the claims of accuracy are elevated because they do not reflect real-life testing in real-life situations. The results from a University of New Mexico study reveal the chances you can anticipate getting the right answer from an early home pregnancy test:
- One day past your expected period: 100% of pregnancies detected
- On the day of your expected period: 96% of pregnancies detected
- On the day before your expected period: 93% of pregnancies detected
- Two days before your expected period: 81% of pregnancies detected
- Three days before your expected period: 68% of pregnancies detected
- Four days before your expected period: 42% of pregnancies detected
- Five days before your expected period: 33% of pregnancies detected
- Six days before your expected period: 25% of pregnancies detected
Dont Read The Results Too Early
Likewise, avoid reading your pregnancy test results too early. As your urine travels through the test indicator window, it might look like the results are showing, but the test needs time to completely work. Follow the testâs instructions as closely as possible and avoid checking on the results too early. If needed, set a timer to let you know, according to the instructions, when the results are ready.

Do You Take A Pregnancy Test In The Morning Or At Night
The best time of day to take a pregnancy test is in the morning, with your first urine of the day. The hCG levels in your urine are highest at this time of day and most likely to be detected by an HPT. However, if you are testing past the first day of your expected period, you may still receive a positive test result if you take a pregnancy test at night. This is because hCG levels are high enough to be detected at any time of day.

When To Take A Pregnancy Test
You should wait to take a pregnancy test until the first day of your missed period. Since HCG is only present once implantation of the egg occurs, there often isnt enough of the hormone to be detected until you miss your menstrual cycle.
Pregnancy tests pick up the hormone secreted after implantation, which usually occurs about two weeks after the sperm meets the egg, says Dr. Culwell. For women who have regular periods, this usually means that HCG can be detected as soon as you miss a period.
This, of course, assumes you have a regular menstrual cycle that can be easily tracked and predicted. If this isnt the case, you may choose to instead track ovulation, or when an egg is released and makes its way to the uterus where it can potentially be fertilized. An at-home ovulation predictor kit can help you track fertilization.
If this method is used, its best to take a pregnancy test approximately 14 days after a documented ovulation, says Zaher Merhi, M.D., an OB-GYN, reproductive endocrinologist and founder of Rejuvenating Fertility Center with locations in New York and Connecticut.

What Is The Best Time To Take Pregnancy Test
Morning is considered the perfect time to take the pregnancy test. This time is best especially if your period is not late or if its late by just a couple of days.
A home pregnancy test works by detecting the hCG hormone in your urine. Unless you get up in the night and pee often or drink water throughout the night, your urine is more concentrated in the morning when you wake up.
This means that the amount of hCG is a bit more, and you are likely to get a pregnancy positive result if you are pregnant.
However, you can take the pregnancy test any time of the day be it the middle of the day or night. In this scenario, you are more likely to get a false negative result, especially if your period is not that late or if you have consumed a lot of water and your urine is diluted.

In the early stages of pregnancy, the rise in hCG levels
8 days after conception. As the pregnancy progresses, levels rise by around 50% a day. HGC is detectable in urine a few days later than in the blood.
Tests for home use are urine tests. A person will need to go to a healthcare facility for a blood test.
A range of pregnancy tests are available for home use, and some are more sensitive than others. This means they can detect hCG at lower levels.
Many tests claim to be 99% accurate, but experts note that not all of them undergo rigorous scientific testing. A person may also get a false-negative result if they take the test too early, do not follow the instructions precisely, or do not handle the test as the manufacturer intended.
Some medical bodies suggest taking a test on the first day of a missed period, but many people do not know when their period should arrive, for example, if they experience irregular menstruation.
When taking a test, a person should:
- read the instructions carefully
- ensure they handle the test as advised
- try to avoid taking the test too early
When Is It Too Early To Test For Pregnancy
If you take a pregnancy test before you have missed your period, you increase your chances of getting a false negative result. This means the test will read negative when you actually are pregnant, so experts recommend waiting until you have already missed your period to prevent false-negative test results.

When Is The Best Time To Take Pregnancy Test
If youre trying to get pregnant, the best time to take a pregnancy test is one week after youve missed your period. Why? Because this is really the best way to prevent a false negative result result.
Home pregnancy tests can be used as early as the first day after your first missed period in women with regular/predictable monthly menses. If you have irregular periods, you can administer a test 14 days after intercourse, since you likely cant pinpoint your exact time of ovulation.
Pregnancy tests detect a hormone called human chorionic gonadotropin , which is produced in early pregnancy. The production of this hormone begins slowly and increases as the pregnancy grows. Standard urine pregnancy tests will detect the HCG level when it reaches 20-50 milliunits/milliliters.
If you take a test too soon , the levels of HCG may not be high enough to detect a pregnancy and it could cause a negative result, even though youre actually pregnant.
I advise my patients to wait at least one day after you miss your period. If you wait one week after a missed period, the chance of a false negative is very low if you have a normal monthly menstrual cycle.
When Should You Take A Home Pregnancy Test
Most home pregnancy tests advise you to take the test after you miss your next period. If you have a standard 28-day cycle, you’ll be most fertile two to three weeks before your period.
So if you get pregnant during that fertility window, you’ll need to wait at least 14 to 18 days after conception to take a home pregnancy test.
If you get a negative result and suspect you’re pregnant, check the instructions on the box. Home pregnancy tests typically recommend retaking the test 5 to 7 days later, when the hCG levels in your body will be higher.
This type of result is called a “false negative.” Sometimes you can receive a false negative result if you take a pregnancy test too soon when your hCG levels are too low for the test to detect them accurately.
Moreover, recent miscarriages, fertility drugs, and rare hCG secreting tumors can interfere with the results of at-home urine tests. If you receive conflicting results after taking a home pregnancy test multiple times, doctors recommend a blood test.

When To Take A Pregnancy Test After Missed Period
If you have missed your period and are wondering whether you might be pregnant, you may be wondering when to take a pregnancy test. The answer to this question depends on a number of factors, including how long your menstrual cycle usually is and how regular your periods are.
Generally, most doctors recommend waiting until after you have missed your period to take a pregnancy test. This is because the level of the hormone hCG in your system usually reaches its peak about two weeks after you miss your period. If you take a pregnancy test before this peak, you may get a false negative result.
However, if you have a very irregular menstrual cycle, it may be difficult to tell exactly when you missed your period. In this case, your doctor may recommend taking a pregnancy test a few days after you think you may have missed your period.
If you are taking a home pregnancy test, be sure to read the instructions carefully. Some tests may allow you to test a few days before your missed period, while others may require you to wait until after you have missed your period.
If you are pregnant, early detection of pregnancy is important for making sure that you receive the appropriate care and treatment. If you are not pregnant, early detection can help you to begin trying to conceive as soon as possible.
Can Any Medication Or Medical Conditions Affect The Result
Testing too soon after using fertility drugs that contain hCG can give misleading results. If you have recently stopped taking hormonal contraception or are using fertility treatments such as clomiphene citrate, your periods may be irregular leading you to test too early.
If you have recently been pregnant you may get a false pregnant result. Ectopic pregnancy, ovarian cysts, menopause and some very rare medical conditions may give misleading results.
If you have a pregnant result it is possible that you later find that you are not pregnant due to loss of the pregnancy in the early stages. Some women who are more than 6 weeks pregnant may get misleading results due to high hCG levels .
If you get unexpected results you should talk about them with your doctor.

Yes, it is possible you could still be pregnant. It’s possible to be pregnant and to have a pregnancy test show that you are not pregnant.
The accuracy of home pregnancy test results varies from woman to woman because:
- Each woman ovulates at a different time in her menstrual cycle.
- The fertilized egg can implant in a woman’s uterus at different times.
- Sometimes women get false-negative results when they test too early in the pregnancy. False negative means the test says you are not pregnant when you are.
- Problems with the pregnancy can affect the amount of hCG in the urine.
If a test says you are not pregnant, take another pregnancy test in a few days. If you are pregnant, your hCG levels should double every 48 hours.1 If you think you are pregnant but more tests say you are not, call your doctor.
How Long Should I Wait Before Taking A Pregnancy Test
Pregnancy tests only work when the pregnancy hormone human chorionic gonadotropin has built up in your system. This usually happens around 11 12 days after ovulation. Most women get their period around 14 days after ovulation.
If you dont know when you ovulated, you can approximate this window by taking a pregnancy test two days before your period is due.
Keep in mind that if you test before your period is due, you may get only a very faint line on the pregnancy test.

Some symptoms of pregnancy include a desire to eat certain foods. Women may experience gastrointestinal changes, and may even notice a change in their urinary habits. If the woman had sex recently and still noticed these symptoms, then she should undergo a urine pregnancy test.
Some people can be confused about when to start a pregnancy test. However, it is best to wait for seven days and notice the appearance of other symptoms. During the period of missed periods, it is best to be tested at the moment when the woman has an episode of irregular periods.

Pregnant women should be aware that hCG is secreted the same way as during their menstrual cycle. Therefore, one should conduct the tests within a suitable time frame to receive the best results. Tests performed by the doctor or a close friend are more reliable than self-administered tests.
If the woman gets a positive result, then she should go through frequent checks to determine if she is really pregnant. However, some women will get a false positive result. In this instance, she should visit her doctor to figure out why she is not pregnant.
