How to Make a DIY Bleach Pregnancy Test: Things You Need to Know

Curious about do-it-yourself pregnancy test methods? More and more women are trying out new ways of determining if they are, indeed, expecting. This article will focus on how a bleach pregnancy test works! 


I’ve tried the bleach method once, and the process went smoothly! Below, I’ll teach you on how to do this DIY pregnancy test, and provide you some tips as well.

There will also be some caveats, so I hope you read this article till the very end!

Important Things You Need To Know About a Bleach Pregnancy Test

Pregnancy tests sold in pharmacies aren’t cheap, so many women opt for the more affordable methods. Bleach, a common household item, is one of the most affordable ways for you to find out if you’re pregnant.

As with most pregnancy test methods, this does not assure that you’ll get accurate results, so do not fully rely on your bleach pregnancy test results. It is a very potent chemical, so you should also be very careful in handling it!

Things You’ll Need

​1. Bleach

​Pregnancy test kits check for the presence of hCG (human chorionic gonadotropin), a pregnancy hormone present in a pregnant woman’s blood and urine. This hormone produced after a fertilized egg is attached to your uterus.

​Because bleach reacts well with hCG, it is commonly used in DIY pregnancy testing.

​For this test, use the regular household bleach—the type that you would use for cleaning or laundry. Don’t the scented ones, as these would have added chemicals.


2. Two Cups

You will need two cups for the test. I’ll be labeling them as Cup 1 and Cup 2.


Step 1. Prepare the urine in Cup 1.

Directly urinate in the cup – this might get messy if you’re not careful, so make sure that you will be able to catch all of your urine while you hold the cup.

Try to fill the cup with up to ¼ cup of urine. And do not forget to wash your hands before and after you pee.

The reason why you’re doing this first is, so you will not have any trace of bleach in your hands. Bleach is toxic, and you do not want any of it near your sensitive areas!

Morning is the best time to do a pregnancy test--the time of the day when a woman can have the highest concentration of hCG so that it can give you better results.

Step 2. Prepare the bleach in Cup 2.

Using a disposable spoon, put bleach some into the cup. There is no specific measurement for this, but I suggest that you use at least two tablespoons or about ¼ cup.

I suggest you use a disposable spoon so you can throw it right away. Bleach can cause irritation. It’s also important that you do this experiment outside or in an open space.

Since you’re dealing with a chemical, you’ll need some fresh air to prevent you from inhaling potential toxins.

When inhaled, bleach can produce harmful fumes that are more dangerous to pregnant women. If you are indeed, pregnant, this is something that you don’t want for you and your baby!

If you need to do this process inside, you should consider covering nose and mouth with a clean towel, or use a disposable face mask (available in most pharmacies). Use anything that will not let you inhale the bleach!

Step 3. Add your urine to Cup 1.

Add the contents of Cup 2 (urine) to Cup 1 (bleach).


You will be able to see the reaction immediately, in a matter of seconds! If the bleach and urine solution starts to form thick bubbles or frothy (not unlike beer looks like after it’s poured into a glass), this could suggest that you are pregnant.

On the other hand, if there’s no change going on in the solution - if there is no froth formation - there’s a bigger chance that you are not pregnant.

When I first did this experiment, I tried it with other urine samples (my sister who is my age and is 100% sure she’s not pregnant, and my husband). Both of their samples didn’t change much, and mine had a very pronounced froth!

True enough, I soon found out that I was, indeed, pregnant.

However, I made sure that I followed this up with an over-the-counter pregnancy test, and then a blood test by a doctor.

Step 4. Visit your doctor.

This is an extra step for those whose results point to pregnancy, those who want to confirm the test or those who are simply curious!

While I do recommend DIY methods and science experiments like this one, I still strongly suggest that all women who think they are pregnant should visit the doctor to confirm. This is still the way to go about it!

I repeat: this test is not accurate, and only your doctor will be able to officially confirm if you’re, indeed, expecting. If you don’t want to consult a doctor just yet, home pregnancy tests from pharmacies are your best bet.

Final thoughts

Did you enjoy the tutorial? I sure hope so! I’m always on the lookout for DIY projects that will help me save money and experiment, so I had a great time writing this article for you!

I cannot stress this enough: be careful! While bleach is an efficient and versatile chemical, it is also strong—potentially harmful if you don’t do it right! You have to be extra careful in handling it.
