Reason being that the egg is fertilised in top third of Fallopian tube and then has to travel but you know, it's microscopic and there is blood flow churning it like a washing machine in there.
It's got to find a place to hang on. Cell divisions also have to take place before it can bury itself in. HCG isn't produced from conception but from implantation. Before it implants, you don't produce HCG so a test will always be negative and for the first days after implantation it will be too , even if there's things happening.
HCG this comes from the placental cells ,which have to attach first so to speak. In the blood it slowly rises , generally doubling every hrs but rates of doubling vary a lot from individual to individual. Kidneys then take days to process it so earliest average result would be 11 dpo , more likely 13 dpo. This is generally why people get a result either way just before period and why it's recommended to wait. However , some women can implant as early as 5 dpo so therefore the kidneys get the signal to do their thing and the test picks up on HCG in wee a few days later.
This early result is an exception rather than the general rule though so def don't feel disheartened if you get a negative before your period is due.
Before then , nothing is certain. Oh and also depends on miu of the test your using. CB are usually last to detect with a higher miu of Mine of coffee aversion. No positive pregnancy test yet but I feel exactly like I did with other two.

As a result, depending on the time of conception, it is possible for women to feel some symptoms of pregnancy this early on. Pregnancy tests are not accurate at 5 DPO, but some women later find that their early symptoms were indeed due to pregnancy. At 5 DPO, if the sperm has reached and fertilized the egg, the cells within the newly formed zygote begin multiplying to create a lump of cells called a blastocyst.
These cells continue to multiply as the blastocyst makes its way down the fallopian tubes and into the uterus. When the blastocyst reaches the uterine wall, it attaches itself to get access to nutrients through the blood.
At 5 DPO, the blastocyst may either be traveling to the uterine wall or already connected to it. If it is attached, the blastocyst has started its journey toward becoming a fetus, and pregnancy is underway.
The specific symptoms of pregnancy vary hugely from woman to woman. Women may experience cramps very early on in pregnancy. These are due to implantation, which is when the fertilized egg attaches to the lining of the uterus.
Implantation cramps may occur a few days after ovulation, and many women say that they feel cramps around 5 DPO. These cramps may occur in the lower back, abdomen, or pelvis. Around 25 percent of women may notice slight bleeding around the time of implantation. This is called implantation bleeding, and it tends to be lighter in color and flow than a menstrual bleed.
Many women keep track of their basal, or baseline, body temperature while trying to conceive because it changes throughout the menstrual cycle. The temperature increases after ovulation and may stay higher than usual until the period begins.
A basal body temperature that remains unusually high beyond the typical length of time may indicate pregnancy. However, these signs are not unique to pregnancy and can be due to another hormonal or lifestyle factor.
According to the National Institutes of Health , other early signs and symptoms of pregnancy may include:. What kind of tests have you been using? They might not be sensitive enough. If for instance you ovulate, and the sperm is there to fertilize immediately and the new life heads down and in just 4 or 5 days, implants.
By the time you test at 8 dpo it has been implanted for possibly 4 days. If the HCG level starts at 5 and doubles in less then 48 hours, then by 8 dpo it could already be as high as 15 which is detectable by some tests. However, if the sperm and egg meet just a few hours later and fertilization occurs and then they travel down into the uterus but do not implant for what can be 12 days later.
Your HCG level will be 0 at 8dpo, at 12 dpo if it implants and HCG is at 5 and it take about 4 days to reach 15 then you would not get a Positive test until at earliest maybe 16 dpo. And some women do not have enough HCG to detect for a long time.
