As you may or may not know already, implantation bleeding represents the process of egg`s invasion into the uterine lining. At that point, there`ll be a few vessels affected, an event that is known as implantation bleeding.
To acknowledge that she`s pregnant, a woman needs to take a blood sample in a doctor`s office or a home pregnancy test. These tests are based on the detection of the pregnancy hormone (hCG) from a urine sample.
Whether the results of these tests are reliable or not usually depends on this hormone`s level at a particular stage. Regular pregnancy tests are most accurate after implantation bleeding. However, there`re early pregnancy tests available on the market as well, and these can provide a positive result just a couple of days after conception (before implantation bleeding).
There are early pregnancy tests which are able to provide a positive result only a couple of days after conception. However, the real confirmation of a pregnancy can only be provided by a doctor after taking a blood sample and ultrasound examination.

About Implantation Bleeding
Implantation represents one of those very first essential moments in the development of the fetus. It will involve a constant invasion of the embryo into the thick endometrial lining.
The implantation process occurs in 3 different stages:
- Egg`s attachment.
- Egg`s implantation in the uterine lining (occasionally also accompanied by implantation bleeding).
- Fetal final fixation and healing of the uterine lining, which was affected during egg`s invasion.
The process begins on the sixth day after conception and is totally complete on the 12th one. Implantation is accompanied by secretion of a substantial range of bioactive substances and hormones coming from the fetus itself and specific structures of the organism of the mother. Chorionic gonadotropin hormone is particularly produced at this point.
Can You Take a Pregnancy Test during Implantation Bleeding?
Yes, theoretically, you are able to take a pregnancy test when implantation bleeding occurs. Still, that does not necessarily mean you`ll also receive a positive result.
There is real way of knowing for sure if the implantation bleeding you may have experience isn`t just early spotting that may indicate your period is near. There may be not enough amount of hCG in our body to register on pregnancy tests.
You need a level of at least 5mI/U to consider yourself pregnant. Since any normal woman has around 1 – 4 mI/U on a regular day, it very much depends on your own body to get a positive pregnancy result.
Still, it may be safe to assume you won`t get a positive pregnancy result during implantation bleeding. If you cannot wait until your first period day, which is when most pregnancy tests are accurate enough to detect the hCG hormone, you may at least wait a couple of days after your suspected moment when you think implantation bleeding may have occurred.
Note: You should be aware that the levels of hCG are always lower in women who carry a male fetus than in women who carry a female fetus.
How Many Days to Wait until Testing After Implantation?
According to most studies, it takes around 2 or 3 days after implantation occurs to be enough amount of hCG in the woman`s body to be detected by most early pregnancy tests. If you do take the test and the result comes out negative, don`t worry! Just wait a few more days and repeat the test using another early pregnancy test. These are a lot more sensitive in detecting that specific amount of hCG.
Is Pregnancy Test After Implantation Bleeding Reliable?
Even if you calculated how many days to wait to get an accurate pregnancy result, you should still remember, for instance, when ectopic pregnancy is involved the level of hCG increases less intensively and slower.
Besides this, threatened miscarriage causes reduction of the level of pregnancy hormone as well. These unbiased theories aren`t free from exception (around 15% – 17%)!
Still, the alternative of false negative test is within the sphere of probability. Comparably, a false negative result can appear because the testing has been too early (when the level of hCG hormone hasn`t yet reached the minimal score to be able to be detected.

Causes of a false positive result:
- Lab error.
- A tumor which produces hCG.
- Lipidemia (the blood contains high lipid content)
- Hemolysis (blood cell destruction.
Spotting & Positive Pregnancy Test
Some drops of red or brown discharge in early pregnancy are also considered as spotting. This happens in 20% to 30% of expecting mothers, generally around a missed period. And most such women continue delivering healthy babies without any issue.
Implantation bleeding generally occurs 5 to 6 days after ovulation starts. If you take a pregnancy test and the result is positive, then you should consider that implantation happened around 4 – 5 days earlier and is less likely for spotting to in fact represent implantation bleeding. – Visit this page!
If your HPT is positive and you notice yourself experiencing spotting along with cramping or pain, you need to get in touch with a doctor as soon as possible. The doctor will be able to check the pregnancy`s viability by simply doing 2 blood tests, 48 to 72 hours apart. You have a viable pregnancy if the levels of hCG are more than double.
How to Confirm a Positive Pregnancy Test after Implantation?
Getting a positive test 6 to 8 days after implantation (days 26th to 28th for a regular 28-day menstrual cycle), it`s best advisable when wanting to confirm a pregnancy result. For this to be accomplished, you need to be very careful to pregnancy signs like:
- Late period.
- Frequent urination.
- Intensive skin pigmentation (linea nigra including).
- Nausea & vomiting.
- High fatigability.
However, a 100% confirmation of a pregnancy should only be up to the doctor, who will have to perform an ultrasound investigation.
