Signs of Pregnancy/The Pregnancy Test

What are the signs of pregnancy?

The signs of pregnancy vary from woman to woman. Usually the most obvious sign is the absence of menstruation (amenorrhea). However, some women continue to have bleeding even while pregnant. The following are the most common first signs of pregnancy. However, each woman may experience the signs of pregnancy differently. These may include:

• Extreme tiredness

• Sore and swollen breasts

• Nausea or vomiting (also called morning sickness)

• Frequent urination

• Certain food cravings or aversions

• Bloating of the belly

• Darkening of the skin around the nipples (also called the areola).

These early signs may not positively indicate pregnancy, but may actually signal another process happening within the body. A pregnancy test can provide more accurate results.

What is a pregnancy test?

Pregnancy is confirmed with a pregnancy test. A pregnancy test can be done on either urine or blood. Pregnancy tests find the presence of human chorionic gonadotropin hormone (hCG). This is a hormone made by the placenta about 10 days after fertilization. Levels of the hCG hormone approximately double every two days during the first 60 days of pregnancy. Pregnancy tests that use the woman's blood are done by a healthcare provider usually to get a very early diagnosis of pregnancy or to confirm an at-home pregnancy test. Blood tests are very accurate and can find pregnancy by the second week after conception.

Women can conduct an at-home pregnancy test by testing a sample of urine about two weeks after conception, or about the time a period is due. Home pregnancy tests have become more accurate in the last decade. If the test is used correctly, most home pregnancy tests are 97% to 99% accurate.

Always talk with your healthcare provider to confirm a positive at-home pregnancy test with a more reliable pregnancy test and physical exam. If your at-home pregnancy test results are negative, and you think you are pregnant, you should also talk with your healthcare provider.

If you get a negative pregnancy test but still feel pregnant, you're likely to feel a bit confused. Your first instinct may be to question whether the test may have somehow gotten it wrong, especially if you feel you have pregnancy symptoms. And in truth, false negatives do sometimes happen, although they are rare. A negative pregnancy test indicates one of four outcomes.

1. You Are Not Pregnant

The most obvious answer may also be the most disappointing. If you feel pregnant—with symptoms such as breast soreness and unexplained nausea—it's understandable that you may have assumed you were pregnant. But, there may be other explanations for these symptoms. Some may be incidental or premenstrual; others may, in fact, require medical attention.

If you are suddenly experiencing abnormal periods accompanied by other symptoms, such as cramping or constipation, it’s a good idea to see a doctor and have it checked out.

2. You Tested Too Early

While modern home pregnancy tests have a high level of accuracy, their sensitivity can vary in the early stage of pregnancy. Pregnancy tests are designed to detect the presence of a hormone called human chorionic gonadotropin (hCG). This is the hormone produced soon after the fertilized egg implants in the uterus. While the body starts to produce hCG soon after implantation, it usually takes around two to three weeks for levels to be high enough for accurate detection.

If you test too early, you may, be pregnant, but the test is simply not sensitive enough to pick up any signs of hCG.

If you are convinced you are pregnant and have simply tested too early, take a step back and retest in a week. Levels of hCG tend to double every two days, so the longer you wait, the more likely you'll receive an accurate—and hopefully positive—result.

3. You Had an Early Miscarriage

If you feel pregnant but had a negative test result, you may have experienced a very early miscarriage (also known as a chemical pregnancy). This occurs when there is a problem with the fertilized egg, most commonly a chromosomal disorder that makes the pregnancy non-viable. When the body detects this, it will spontaneously abort the fetus, often times before a person even knows that they are pregnant. Up until this point, however, symptoms of pregnancy may develop as hormones are steadily released into the system.

While an early miscarriage can occur in anywhere from 10% to 20% of known pregnancies, overall rates could very well be in excess of 50%. Miscarriages tend to be a one-off event; most people are able to achieve and maintain a healthy pregnancy in later attempts.

4. The Test Was Wrong

A bum test is the most unlikely cause of a false negative result, but it does happen. However, in almost all cases, some level of human error is involved. Beyond taking the test prematurely, there are other possible causes for a false negative result:

• Diluting your urine by drinking too much water before taking a test
• Not leaving the dipstick in the urine stream for the recommended time
• Using a test that has been exposed to excessive heat or sunlight
• Using an expired test

Lastly: sometimes twin or higher order multiple pregnancies, in which levels of hCG are very high, can cause a false negative pregnancy test. This is called the high-dose hook effect. It's unusual, but possible. if you miss a period and have pregnancy symptoms, see your doctor.

A Word From Verywell

Whatever the results of your pregnancy test, you can get confirmation from your health care provider if you're not entirely sure the test was accurate. However, in most cases, know that home pregnancy tests are highly reliable. So, while this may not be the news you want to hear, if it says you're not pregnant, you likely are not.

Still, in some situations, pregnancy tests do give false negative results, so it is possible to be pregnant even if the test says you're not. Your doctor—or testing again in a few days—can tell you for sure. If you're not pregnant but want to be, and have been trying for a year (or six months if you're 35 or older) without success, contact your doctor to discuss your fertility treatment options.
