What to Expect from Negative Pregnancy Tests After Implantation Bleeding

Implantation bleeding is one of the earliest signs of pregnancy and happens when the ball of cells, that will eventually become the embryo (known also as the blastocyst), attaches itself to the uterus. This attachment can disturb the lining of the uterus to the point where slight bleeding may occur. This is a natural process, which simply means everything is progressing as it should be. While implantation bleeding is one sign of early pregnancy, there are several others. Another way to confirm that you might be expecting a child is to take a home hCG test. There are instances, in which implantation bleeding has already occurred, but yet the desirable second line is not visible. We’ll tell you the reasons, why this might happen. Mostly it has nothing to do with the test itself being defective. The negative result is also not sure fire proof that you are not actually pregnant. Read on to learn, why this might be the case.

Common Early Pregnancy Symptoms

A woman’s body is great at giving her clues that she might be pregnant. Even before you were due for a regular menstrual period, implantation bleeding may occur. This will usually be just a slight spotting, typically occurring around a week before your period would be normally be due. The bleeding is generally sparse and can last for as short as a few hours to about two or three days. Many women may even interpret this spotting as just a light discharge between periods, or as the start of early menses. But aside from this sign, if the body is really pregnant, you’ll soon figure it out, with or without a hCG test.

A missed period is obviously a sign of successful conception, but even before than happens, a woman may start noticing a few other things. Breasts may become tender and feel fuller or heavier. You may experience nausea or morning sickness. Certain smells that never bothered you before may repel you. You may find that you need to urinate more frequently, even if you haven’t increased your intake of liquids. You may also feel very tired, or be experiencing some unusual changes in mood. Another common early pregnancy symptom is dizziness upon rising quickly from a lying or sitting position.

Pregnancy Tests and Their Accuracy

If you feel you’ve experienced implantation bleeding and now want to confirm the pregnancy, you can always perform a home stick-test. Such “device” works by detecting the hCG in the urine. A woman naturally has a small amount of this hormone in her urine on any day, but this number increases greatly after conception. In order for the pregnancy test to read the result as “positive”, the hCG level must be at least 5mIU. The majority of home tests, which are available today, are treated as “fair”, with some boasting a 99% accuracy rate. Some of them claim they can detect a new state of being an “expectant” as early as three to four days before menses, while others claim to detect it as early as the day after missing a menstrual period.

Always make sure to follow the directions on the test package, and even while some say you can collect your urine at any time of day, the first morning urine always has the highest concentration of hCG and will likely give the best and the earliest result. Some brands use a urine collection cup, while other tests look like a thin strip with markers. The ones, labeled “early pregnancy tests”, will likely give the most accurate results during the first weeks after conception. Different brands vary in sensitivity (as in how early they will detect a new state), ease of use, and price. If you want a foolproof pregnancy test method, visit your health care provider for a blood test. It will detect an embryo developing even if the HPT is negative.

Why Some Tests Are Negative During Implantation Bleeding?

So you’re fairly certain you’ve experienced implantation bleeding, took a hCG test to confirm the pregnancy, but got a negative result. How could this be? Was the test defective? Did the test lie to you? Chances are that you took the test too soon after implantation bleeding, before the hCG hormone had plenty of time to reach high enough levels to be detected. If it is below 5mIU, you could still be pregnant but it is simply too early to indicate this fact. Nevertheless, the capabilities of home tests are limited. The good news is, you usually only need to wait a matter of a few days in order for the hormone to build enough to be detected and to receive a positive result. Its level doubles every 2 days.

In rare instances, implantation bleeding may have occurred, but the blastocyst may have failed to thrive, resulting in a very early miscarriage that would likely go undetected by someone, who hadn’t yet thought they were pregnant. Chances are that the bleeding would then be dismissed as a regular menstrual period. In some cases, when a woman feels she has experienced implantation bleeding, it may not be this at all. Sometimes there is just a bit of blood that remained in the uterus. It just happens to be expelled around the time frame when implantation bleeding would likely occur.

None of these instances have anything to do with the pregnancy test “lying” to you, but are rather just the limitations of the test as to how early it can detect the hCG hormone. In the other cases, there is no longer a state to be detected, or there never was a conception in the first place.

Conclusion

If you feel certain you have experienced implantation bleeding, but your pregnancy test came out negative, you may still actually be pregnant. If you are not having any signs of trouble with your new state, wait a few days more and then retake the test. The most reliable results you can get after calling your doctor. He or she will schedule a blood test and an ultrasound to confirm or rule out pregnancy.
