Get a false positive pregnancy test? If you are trying to become pregnant, then the desire to take a pregnancy test may be strong and powerful. Most of women find it impatient to wait for their period to be late. Instead, they decide to test as early as possible. However, it is worth remembering that testing before your expected menstrual period is a main cause for false positive pregnancy test results.
Of course, a false-positive pregnancy test may be confusing and devastating, especially for those who have difficulty conceiving or even those who are actively trying to get pregnant. Luckily, such false positives are rare, although they may even happen for plenty of reasons. Today, let’s explore some common causes through reading this article right now!
So, how does a pregnancy test work?
In general, at-home pregnancy tests check for the amount of human chorionic gonadotropin (or hCG). Such the hormone is produced by the body during pregnancy. As a fertilized egg tends to attach to the uterine lining, then the placenta forms as well as produces hCG. A urine test may detect hCG about 12 to 14 days after conception. Meanwhile, a blood test can detect it about 11 days after conception. Throughout 8 to 11 weeks of pregnancy, a mom’s hCG level usually doubles every 72 hours. After that, it often remains consistent and then decreases after delivery.
Typically, an at-home pregnancy test usually detects hCG in urine. So, if the hormone is available, it will trigger a chemical reaction. In that case, the test will show that you are now pregnant. What if hCG isn’t present? Then, the test will show the sign that you are not pregnant. On the whole, 2 lines in a test mean that you’re pregnant. And 1 line means you’re not. However, the result just depends on the test brand. For instance, some tests use “+” and “-: signs.
Why can you end up with a false positive pregnancy test?
Let the pregnancy test sit in the urine too long before looking
Want to take a pregnancy test with line indicators? Then, remember to check the results on time, just like what its instruction says. In case you let it sit too long before seeing the results, then urine on the test may even evaporate. At that time, it can look like you get the result with 2 lines, instead of only one line.
How to avoid this case? It is highly advisable to consult the pregnancy test’s directions carefully. Then, make sure to follow them exactly. Let’s take First Response – one of the popular pregnancy test brands as a typical example. This test usually instructs women to wait 3 minutes before reading the result.
The pregnancy test seems to be expired
One of the causes for false positive pregnancy test is that you are using the expired test. Once the test’s expiration date is over, the chemical which detects hCG seems not to work as expectation. In that case, you are quite able to get a wrong result.
Take fertility medications that even can raise hCG levels
Try to get pregnant under a healthcare provider’s care? Then, you can be on fertility medications. In fact, one of these may be the synthetic hCG trigger shot under the brand names, like Ovidrel, Novarel, Pregnyl, and Profasi. Basically, the hCG shot usually helps follicles to release mature eggs. At the end, it can cause a false-positive result on one at-home pregnancy test. This is especially true if the test is done too early.
Have had an early miscarriage
You could get your menstrual period a few days after a positive test and then assume you have had a false positive pregnancy result. But, this sign can show that you were pregnant but miscarried early on. Actually, the test is not wrong. Instead, it was quite accurate at picking up hCG. Unfortunately, this is not called a healthy pregnancy.
To be sure, most of the miscarriages happen in the first 13 weeks of pregnancy. For sure, there are no real statistics about this case. However, it’s still estimated that many miscarriages take place before the mom knows she’s pregnant. When does a chemical pregnancy occur? It is about a pregnancy is shortly lost after implantation. It often happens, because of chromosomal abnormalities in the fertilized egg.
Ladies who have a chemical pregnancy tend to notice bleeding right around the time of their period. That’s why they usually assume that they have had a false-positive test result.
Still have residual hCG levels in your system after a miscarriage or a delivery!
hCG may persist in your body for a few months, even after you miscarry or give birth! Normally, it takes about 4 to 6 weeks for the hCG levels to return to normal after you suffers a miscarriage. The reason is that some of the placentae may be still left behind in the body. Thus, it may totally continue to produce hCG within a short period of time.
What to do now? Consider contacting your doctor immediately!
The best way to confirm the false positive pregnancy test is to visit your doctor. In brief, he may do a blood test to further determine the hCG levels. He also wants to clear up potential pregnancy test errors. It is interesting to know that a blood test can give you an accurate result even up to 90%. So, this diagnostic test can let you know whether you are actually pregnant not. Does the blood test confirm you become pregnant? The doctor then continues to monitor hCG levels in your blood. His aim is to ensure that the pregnancy is properly developing before an ultrasound performance can reveal more details.
What if you have a negative pregnancy test? Then, accept the fact that a false negative is possible. When an at-home pregnancy test is done too early, it may not pick up the hCG hormone. The longer you are patient to wait, the more likely you are to confirm the pregnancy!
