When tests are positive, but the H.C.G. levels are not high, and you experience your first period a couple of days or one week later than what you were expecting, this is a biochemical pregnancy,” says Dr. Knopman.

It means you have high levels of pregnancy hormones in urine or blood tests. In essence, sperm fertilizes an egg, and an embryo was born -even implanted -however, it didn’t move as far as she claims.

A majority of cases of loss of pregnancy early are due to chromosomal disorders, according to the ACOG, which is the American College of Obstetricians and Gynec.

2. Ectopic Pregnancy.

Fertilized eggs link to the uterus in a normal pregnancy. However, the term Ectopic pregnancy, a fertilized egg becomes stuck on the way to the uterus. It then grows, typically in the fallopian tube.

If this happens, you may be able to get a false positive pregnancy test because your body releases H.C.G. However, fertilized eggs can’t live in the uterus. If you don’t naturally miscarry, you feel intense pelvic or abdominal bleeding, severe fatigue, or shoulder pain.

Ectopic pregnancies can trigger your fallopian tube to burst, which is life-threatening without treatment.

3. Molar pregnancy

A Molar pregnancy, also known as a hydatidiform molar, is a condition that causes a tumor in the uterus. In contrast to a normal embryo and placenta, the placental tissue is abnormally developed.

It can lead to an accumulation of cells or a mass of tiny sacs of fluid, which a physician has to eliminate by performing the dilation and curettage process, also known as D&C. D&C.

No placental tissue or embryo is present in the growth rested Source in an entire Molar pregnancy. In contrast, when a partial molar pregnancy occurs, it is possible to find baby tissue inside the growth of the molars.

In a molar pregnancy, HGCG levels in a woman will rise. It leads to the false positive pregnancy test.

4. Miscarriage or Abortion

If a person is taking a home pregnancy test for urine within a short time after having a miscarriage or an abortion may be a reason behind the false-positive result.

hCG levels decrease as early as five days after an abortion. Still, it remains at a detectable level.

A few women might also experience an incomplete miscarriage. It indicates that a tissue created during pregnancy in the uterus that is producing the hormone hCG. If this happens, the patient will require surgery trusted Source to eliminate all remaining pregnancy tissues.

5. Expired Pregnancy Test

The most frequent reason for false positives in patients is the expired test. If a test has passed its expiration dates, the substance that detects hCG does not always function.

The test can expire, and the likelihood of getting false positive pregnancy test,” Dr. AbdurRahman declares.

6. Some Medications Can Trigger False-Positives

If women struggle to get pregnancies, her physician recommends fertility treatments. Some of these medicines contain the hormone hCG, which aids in releasing mature eggs in a woman’s ovary.

A false positive can occur if you test for pregnancy within 7-14 days following fertility treatments. It suggests delaying pregnancy tests until about a week after the last treatment or injection.

Be sure to inform the doctor if taking any medication as various drugs can lead to false positives.

7. There Is Still hCG In Your Body After Birth Or a Delivery

The majority of miscarriages occur during the beginning of the first 13 weeks of pregnancy. While there aren’t any accurate figures, many miscarriages occur before the woman even realizes they’re expecting.

According to the doctor, hCG remains throughout your body for months after giving birth or miscarrying. Williams says.

A research study published in The Journal of Clinical Endocrinology and Metabolism suggests that hCG levels can take anywhere from four to six weeks to return to normal levels following a spontaneous miscarriage.

Some placentae may be left in the body and can continue to release hCG over only a few days. “As there are viable and growing placenta cells and the tests are conclusive,” Dr. Williams declares.

8. Test Did Incorrectly

Always read the instructions on the label before using an at-home pregnancy test. Note the time to determine the results, and that specific test results can alter after a particular time.

Also, before performing the Test, cleanse your genital area using water. Certain creams or soaps could change the test results and result in false positive pregnancy test.

9. Evaporation Lines

Sometimes, an evaporation test can be mistakenly interpreted as a positive pregnancy test. At-home tests may show two lines if hCG has been detected and one if hCG has not.

These lines’ colors are mostly bright, such as blue, red, and pink. Sometimes, a faintly colored second line will appear. It indicates an early pregnancy or an evaporation area.

If the line is completely colored, it’s likely to evaporate. If your urine has wholly disappeared, evaporation lines might be visible on a test.

Evaporation lines can sometimes occur due to hormone levels that aren’t indicative of pregnancy. To avoid being confused by an erosion line, it is essential to follow the timing instructions precisely.
