Pregnancy tests work by detecting the presence of the hormone human chorionic gonadotropin (hCG) in a woman's urine. hCG is produced by the placenta and is only present during pregnancy. The amount of hCG in a woman's urine increases rapidly during the early stages of pregnancy, so a pregnancy test can be positive as early as 10 days after conception.
However, it is important to note that not all pregnancy tests are equally sensitive. Some tests can detect lower levels of hCG than others. This means that a woman may get a negative result on one test and a positive result on another test. If you are unsure about the results of your pregnancy test, it is best to take another test or to see your doctor.
In this article, we will discuss the factors that affect how soon a pregnancy test will read positive, as well as the different types of pregnancy tests and their accuracy.
How Soon Will a Pregnancy Test Read Positive
Here are 8 important points to consider:
- hCG hormone detection
- 10 days after conception
- Sensitivity of pregnancy tests
- False negative results
- False positive results
- Missed period
- Early pregnancy symptoms
- Doctor's confirmation
If you are unsure about the results of your pregnancy test, it is best to take another test or to see your doctor for confirmation.
hCG Hormone Detection
Human chorionic gonadotropin (hCG) is a hormone that is produced by the placenta during pregnancy. It is responsible for the changes that occur in a woman's body during pregnancy, such as the thickening of the uterine lining and the production of breast milk.
- hCG levels rise rapidly:
hCG levels rise rapidly in the early stages of pregnancy, doubling every 2-3 days. This means that a pregnancy test can be positive as early as 10 days after conception.
- Pregnancy tests detect hCG:
Pregnancy tests work by detecting the presence of hCG in a woman's urine or blood. The most common type of pregnancy test is a urine test, which can be purchased over-the-counter at most pharmacies.
- Sensitivity of pregnancy tests:
The sensitivity of a pregnancy test refers to the lowest level of hCG that the test can detect. Some tests are more sensitive than others, meaning that they can detect lower levels of hCG. This means that a woman may get a positive result on one test and a negative result on another test.
- False negative and false positive results:
False negative results can occur if the test is taken too early in the pregnancy, before hCG levels have risen high enough to be detected. False positive results can occur if the test is contaminated or if the woman is taking certain medications.
If you are unsure about the results of your pregnancy test, it is best to take another test or to see your doctor for confirmation.
10 Days After Conception
Conception occurs when a sperm fertilizes an egg. After conception, the fertilized egg travels down the fallopian tube and implants in the lining of the uterus. This process, known as implantation, usually takes place 6-10 days after conception.
Once the fertilized egg has implanted in the uterus, it begins to produce the hormone human chorionic gonadotropin (hCG). hCG is responsible for the changes that occur in a woman's body during pregnancy, such as the thickening of the uterine lining and the production of breast milk.
hCG levels rise rapidly in the early stages of pregnancy, doubling every 2-3 days. This means that a pregnancy test can be positive as early as 10 days after conception. However, it is important to note that not all pregnancy tests are equally sensitive. Some tests can detect lower levels of hCG than others.
If you take a pregnancy test too early, before hCG levels have risen high enough to be detected, you may get a false negative result. This means that the test will say you are not pregnant, even though you are. If you are unsure about the results of your pregnancy test, it is best to take another test or to see your doctor for confirmation.
It is also important to note that some women may not experience any symptoms of pregnancy in the early stages. This is perfectly normal. Every woman's pregnancy is different.
Sensitivity of Pregnancy Tests
The sensitivity of a pregnancy test refers to the lowest level of hCG that the test can detect. Some tests are more sensitive than others, meaning that they can detect lower levels of hCG. This means that a woman may get a positive result on one test and a negative result on another test.
- hCG levels in early pregnancy:
In the early stages of pregnancy, hCG levels rise rapidly, doubling every 2-3 days. This means that even a pregnancy test with low sensitivity should be able to detect hCG within a few days of implantation.
- Different brands and types of tests:
There are many different brands and types of pregnancy tests available. Some tests are more sensitive than others. The sensitivity of a pregnancy test is usually indicated on the packaging.
- False negative results:
If a pregnancy test is taken too early, before hCG levels have risen high enough to be detected, the test may give a false negative result. This means that the test will say you are not pregnant, even though you are.
- False positive results:
False positive results are rare, but they can occur. This means that the test will say you are pregnant, even though you are not. False positive results can be caused by certain medications, medical conditions, or a chemical pregnancy.
If you are unsure about the results of your pregnancy test, it is best to take another test or to see your doctor for confirmation.
False Negative Results
A false negative result is when a pregnancy test says you are not pregnant, even though you are. This can happen for a number of reasons:
- Taking the test too early:
If you take a pregnancy test too early, before hCG levels have risen high enough to be detected, you may get a false negative result. This is especially true if you are using a less sensitive pregnancy test.
- Using an expired or damaged test:
Make sure that you are using a pregnancy test that is not expired and that has been stored properly. An expired or damaged test may give you a false negative result.
- Not following the test instructions carefully:
Be sure to follow the test instructions carefully. This includes things like collecting the urine sample correctly and waiting the correct amount of time before reading the results.
- Certain medical conditions:
Certain medical conditions, such as kidney disease and thyroid disease, can affect the accuracy of pregnancy tests. If you have a medical condition, talk to your doctor about whether or not you need to take a different type of pregnancy test.
If you get a false negative result on a pregnancy test, it is important to take another test or to see your doctor for confirmation.
False Positive Results
A false positive result is when a pregnancy test says you are pregnant, even though you are not. This can happen for a number of reasons:
Chemical pregnancy:
A chemical pregnancy is a very early pregnancy that ends in miscarriage. Chemical pregnancies are very common, and many women experience them without even realizing it. A pregnancy test may be positive with a chemical pregnancy, but the levels of hCG will soon drop and the test will become negative.
Ectopic pregnancy:
An ectopic pregnancy is a pregnancy that implants outside of the uterus. Ectopic pregnancies can be dangerous and can lead to serious complications. A pregnancy test may be positive with an ectopic pregnancy, but the levels of hCG will not rise as quickly as they would with a normal pregnancy.
Certain medical conditions:
Certain medical conditions, such as ovarian cysts and pituitary gland tumors, can cause a pregnancy test to be positive, even though you are not pregnant. If you have a medical condition and you get a positive pregnancy test, it is important to see your doctor right away.
Medications:
Certain medications, such as fertility drugs and some antidepressants, can cause a pregnancy test to be positive, even though you are not pregnant. If you are taking any medications and you get a positive pregnancy test, it is important to talk to your doctor.
If you get a false positive result on a pregnancy test, it is important to see your doctor right away. This is especially important if you have any symptoms of pregnancy, such as nausea, vomiting, or breast tenderness.
Missed Period
One of the most common signs of pregnancy is a missed period. A period is the monthly shedding of the lining of the uterus. If you are pregnant, the fertilized egg implants in the lining of the uterus and begins to grow. This prevents the lining of the uterus from shedding, and you will not have a period.
Most women have a menstrual cycle that lasts 28 days. However, it is normal to have a cycle that is shorter or longer than 28 days. If you have a regular menstrual cycle and you miss your period, it is possible that you are pregnant.
However, there are other reasons why you may miss your period, such as stress, illness, or a change in your diet or exercise routine. If you miss your period and you are not sure if you are pregnant, you should take a pregnancy test or see your doctor.
If you are pregnant, it is important to start prenatal care as soon as possible. Prenatal care can help you have a healthy pregnancy and a healthy baby.
Here are some other early signs and symptoms of pregnancy:
- Nausea and vomiting (morning sickness)
- Breast tenderness
- Fatigue
- Frequent urination
- Constipation
- Bloating
- Headaches
- Mood swings
Early Pregnancy Symptoms
Early pregnancy symptoms can vary from woman to woman. Some women experience many symptoms, while others experience only a few. Some of the most common early pregnancy symptoms include:
- Missed period:
One of the most common signs of pregnancy is a missed period. If you are pregnant, the fertilized egg implants in the lining of the uterus and begins to grow. This prevents the lining of the uterus from shedding, and you will not have a period.
- Nausea and vomiting (morning sickness):
Morning sickness is a common early pregnancy symptom that usually starts around 6 weeks of pregnancy. It can range from mild to severe, and it can last throughout the pregnancy.
- Breast tenderness:
Your breasts may become tender and swollen in early pregnancy. This is caused by the hormonal changes that are occurring in your body.
- Fatigue:
You may feel more tired than usual in early pregnancy. This is also caused by the hormonal changes in your body.
Other early pregnancy symptoms can include:
- Frequent urination
- Constipation
- Bloating

Doctor's Confirmation
If you get a positive result on a pregnancy test, it is important to see your doctor for confirmation. Your doctor will perform a physical exam and ask you about your medical history. They may also order some tests, such as a blood test or an ultrasound.
- Pelvic exam:
During a pelvic exam, your doctor will check your cervix for signs of pregnancy. They may also take a sample of cells from your cervix to test for pregnancy.
- Blood test:
A blood test can measure the level of hCG in your blood. hCG is a hormone that is produced by the placenta during pregnancy. The level of hCG in your blood will increase as your pregnancy progresses.
- Ultrasound:
An ultrasound is a painless procedure that uses sound waves to create images of your uterus and ovaries. An ultrasound can confirm pregnancy and determine the age of the fetus.
- Other tests:
In some cases, your doctor may order other tests, such as a urine test or a genetic test. These tests can help to rule out other medical conditions and to assess the health of the fetus.
Once your doctor has confirmed your pregnancy, they will discuss your options with you. These options may include prenatal care, childbirth classes, and delivery options.
