When a woman is waiting to see those important lines she can barely wait. It is essential that you understand that waiting for taking a pregnancy test is not to torture you. It instead assures that you get accurate results. Can you get a positive pregnancy test at 3 weeks?

Before answering that you need to understand few things.

You must understand what needs to happen before taking a pregnancy test.

Unless your body has enough hCG hormone you cannot take a pregnancy test. It is because a pregnancy test is a qualitative test and only works by detecting the pregnancy hormone.

When you have sex near ovulation day, you are fertile to get pregnant. After about six to twelve days from implantation, your body starts forming hCG in enough quantities. 

This is a unique pregnancy hormone that comes along your urine and also is present in your bloodstream. 

So it means that it takes about three weeks after conception to have enough hCG.

Can you get a positive pregnancy test at 3 weeks?

So the answer is Yes! Three weeks is the exact time for being most likely to get a positive pregnancy test. 

It is the time where your due period date also falls. A positive pregnancy test at 3 weeks is near period date. 

The dates of implantation bleeding and period overlap and it can be confusing.

Pregnancy tests claim to have 99% accuracy rates. But they always mention a line after that saying – From the day of missed period. 

Before the day of missed period, the hCG levels allow only a low 54% accuracy rate.

Positive pregnancy test: How early after implantation?

Implantation is the process of attachment of baby’s cells to the lining of the uterus. 

After this step, your body starts producing hCG. It takes at least three to five days for producing enough hCG after implantation. 

You can take the pregnancy as early as one week after implantation. If you can risk getting a false negative pregnancy test, then you may test earlier.

A pregnancy blood test can detect pregnancy even earlier since the serum blood levels are higher than urine hCG levels. 

Positive pregnancy blood test after implantation can be as early as three days.

When we say a pregnancy test is 99% accurate after three weeks, it means that out of 100 women taking the test only one will have a false test. 

It also means that a person who has got a positive pregnancy test is 99% likely to be positive and 1% chance exists for it being a false positive pregnancy test. 

A false positive paradox is complicated even for students of medical sciences, and it is okay if you don’t understand it. 

All you need to know is that pregnancy test at three weeks is most accurate when positive.

If you are taking fertility drugs, then you can get a false positive pregnancy test. 

Home pregnancy tests accuracy also depends on how you perform the test. 

If you don’t follow the specific instructions of pregnancy test, then home pregnancy test can give a false positive. 

But the pregnancy test is not fake! It is very genuine and can detect pregnancy mostly. 

Pregnancy test after implantation needs you to wait for the hCG from ovulation drugs (from fertility treatment) to get out of your body. Only after that, you can get accurate pregnancy test results.

When will positive pregnancy test show?

A positive pregnancy test will show after your body has enough hCG. 

The sensitivity of different pregnancy tests is different. Some may be able to detect lower levels of hCG. Others need a higher concentration of hCG for detecting pregnancy. 

Once the hCG level in your body reaches 25 mIU/ml, a positive pregnancy test will show up.

 Beyond this level of hCG mostly every pregnancy test will give a positive. 

You can get a big fat positive pregnancy test after three weeks. 

For getting the highest accuracy of pregnancy test, you must wait for three weeks from ovulation date.
