When to take a pregnancy test

The best time to take a pregnancy test is usually after a missed period, when pregnancy hormone levels are more likely to be high enough to detect. Some early pregnancy test options can work sooner, but accuracy is generally better if you wait until the day your period is due or later. If your cycle is irregular or you are unsure when ovulation happened, timing can be harder to judge, so repeating the check in a few days may help.

How to use a home pregnancy test correctly

Read the instructions first

Home pregnancy test instructions vary by brand. Check how long to hold the stick in urine, whether to dip or stream, and exactly how long to wait before reading the result.

Use first-morning urine when possible

If you are checking very early, first-morning urine may contain a more concentrated level of pregnancy hormone, which can improve the chance of an accurate result.

Read the result in the time window

Looking too early can miss a positive result, and looking too late can lead to confusion from evaporation lines. Follow the package timing closely.

What pregnancy test results can mean

A clear positive result

A positive result usually means pregnancy hormone was detected. Even if the line is light, it can still be positive if it appears within the instructed reading time.

A negative result

A negative result can mean you are not pregnant, or that it is still too early. If your period does not start, checking again in 48 to 72 hours may provide a clearer answer.

A faint line

A faint line on a pregnancy test may happen in early pregnancy when hormone levels are still low. It can also be confusing if read outside the recommended time window, so timing matters.

Reasons a pregnancy test can be wrong

Checking too early

One of the most common reasons for a false negative is taking a pregnancy test before enough hormone has built up to be detected.

Not following instructions exactly

Using too much or too little urine, reading the result too soon, or waiting too long can affect how the result appears and how confident you can feel about it.

Expired or faulty kit

An expired or damaged kit may not work as expected. If the control line does not appear, the result is invalid and a new kit is needed.

Frequently Asked Questions

When is the best time to take a pregnancy test?

For the most accurate result, it is usually best to take a pregnancy test after a missed period. Some early pregnancy test products can detect pregnancy sooner, but results are more reliable once your period is due or late.

How accurate is a pregnancy test?

Pregnancy test accuracy depends on timing and correct use. Many home tests are highly accurate when used after a missed period and according to the instructions. Taking one too early is a common reason for a wrong result.

Can a pregnancy test be wrong?

Yes. A pregnancy test can be wrong if it is taken too early, used incorrectly, expired, or read outside the recommended time window. False negatives are more common than false positives.

What does a faint line on a pregnancy test mean?

A faint line may still mean positive, especially in early pregnancy when hormone levels are lower. It is important to read the result within the brand’s stated time window. If you are unsure, repeating it in a couple of days can help.

What should I do if I get a negative result after a missed period?

If you have a negative result after a missed period, you may have ovulated later than expected or checked too soon for your hormone level. Consider repeating it in 48 to 72 hours and follow the package instructions carefully.
