Faking a pregnancy is a prank that most women can easily pull off. If you believe this joke will make your spouse, friends, or family laugh, the most effective way to deceive them is by faking a pregnancy test result. You have several options to create a fake positive test, from purchasing a fake positive pregnancy test to swapping a real one. To make it even more convincing, mimic early pregnancy symptoms. However, be mindful that individuals struggling with infertility or those who have experienced miscarriages might find this prank upsetting.
Steps
Fake Early Pregnancy Symptoms

Complain about missing your period several days prior. Your prank will seem more believable if you set the stage by mentioning that your period is late. Bring this up several days before you plan to announce the fake pregnancy.
- You could say, “You know, I was supposed to get my period two days ago, but it still hasn’t come. I hope it arrives soon so I can attend Kim’s pool party.”
- If the person you’re trying to trick doesn’t react, follow up with another comment, such as, “I’m worried about what this delay might mean. Do you think something’s wrong with me?”

Pretend to have morning sickness by faking nausea and vomiting. Morning sickness is a common early sign of pregnancy that almost everyone recognizes. You can excuse yourself and rush to the bathroom, splashing water in the toilet to mimic the sound of vomiting. Additionally, “manage” your “morning sickness” by nibbling on crackers, sipping ginger ale, and eating small meals.
- Sprinkle a bit of water on your forehead after pretending to vomit to make it seem like you’re sweating from the effort.
- Strong odors often trigger nausea in pregnant women. Complain about feeling nauseous whenever you encounter a strong smell.

Frequently visit the restroom to pretend you have an increased need to urinate. During pregnancy, your blood volume increases, meaning your kidneys have to filter more fluid. This extra fluid turns into urine, leading to more frequent bathroom trips. Also, complain about how often you’ve been needing to go lately.
- Say something like, “I’m so tired of having to pee all the time; it feels like I can’t stay away from the bathroom,” or “I feel like I always need to go. I hope I’m not pregnant.”
Tip: You can increase your need to urinate by eating water-rich fruits like watermelon, citrus, pineapple, kiwi, tomatoes, plums, bananas, and apples. The higher the water content in the fruit, the more you’ll need to go. Another option is to consume diuretics, such as caffeine and carbonated drinks.

Act as though your breasts are swollen and tender. Hormonal changes in the early weeks of pregnancy can cause breast tenderness, even before you know you’re pregnant. Mention this discomfort to the person you’re pranking. You can even place a warm compress on your chest to “relieve the pain.”
- If you live with the person, draw attention by going braless at home. Say, “Wearing a bra is so uncomfortable right now. I think my breasts are more swollen than usual.”

Pretend to feel constantly tired. During pregnancy, your body produces more progesterone, making you feel more fatigued. This means you’ll start feeling tired very early on. You can mimic this symptom by telling people you’re exhausted. Additionally, take naps during the day or pretend to doze off midday.
- Avoid pretending to sleep at work or school, or you might get into trouble.
- You could say, “I shouldn’t be this tired; I slept for nine hours last night. I don’t know what’s wrong with me.”

Act overly emotional and prone to tears. Pregnancy causes hormonal fluctuations, leading to mood swings. You can mimic this by pretending to cry during commercials or while watching a sad meme. Additionally, get angry over minor things and then pretend to burst into tears.
- For example, show the person a cute puppy GIF, then start crying and say, “Oh my gosh, it’s just too adorable.”

Pretend to crave unusual foods. While cravings don’t typically occur in the early weeks of pregnancy, they are one of the most recognizable signs. If you act like you’re craving strange food combinations, the person you’re pranking will likely think you’re pregnant. You could ask for snacks like pickles and ice cream or request peanut butter to spread on a hot dog. If your stomach isn’t up for it, make a smoothie and list off bizarre ingredients you added.
- You might say, “Hmm… this smoothie is so good. I added pickles and tuna because I suddenly craved it.”
Fake a Positive Test Result

Buying a fake pregnancy test is the easiest option. A fake pregnancy test is the best choice because it always shows a positive result. Purchase one, take it to the bathroom, and use it like a real test. Wait for the result to appear and show it to the person.
- You can buy fake pregnancy tests online or at prank shops.
- Make sure to read and follow the product instructions for it to work properly.
Tip: One downside of fake pregnancy tests is that you might be asked to take another test for confirmation. It’s a good idea to buy a few in case you need to test twice.

Dip the pregnancy test strip into a cup of Coca-Cola or Pepsi. Some ingredients in soda have properties similar to pregnancy hormones, which can cause a false positive result. Bring a can of soda into the bathroom when taking the test. Dip the test strip into the soda instead of urine. Remember to hide the soda can before opening the bathroom door.
- You might be asked to retake the test, so keep an extra soda can hidden in the bathroom just in case. Store it somewhere discreet, like in your makeup bag or tampon box.

Open the pregnancy test and draw an extra line to fake a positive result. Most pregnancy tests have two plastic pieces on the front and back. Use a thin metal tool, like tweezers or a nail file, to pry open the front piece. Then, use a marker in a color similar to the test line to draw a fake positive line. Dab a bit of water on the test to make it look like you’ve used it, then reassemble it.
- A light pink marker works best.
- The result will look more convincing if you draw both lines. This way, you won’t need to use urine on the test.
- Wetting the test not only makes it look used but also helps the drawn lines fade slightly, making them appear more realistic.

Use the test at least an hour before you “announce” the pregnancy. Most pregnancy tests only show accurate results for a few minutes. After that, the urine on the test begins to evaporate, causing the lines to darken and appear positive. You can take advantage of this by testing at least an hour beforehand. When the result looks positive, take it to the bathroom and pretend to test again.
- This trick doesn’t always work, but it’s a common cause of false positives.

Try using an expired pregnancy test for a false positive result. Expired pregnancy tests can also yield false positives, but finding one might be tricky. Ask friends if they have old tests or check eBay for sellers. You can also look for them at thrift stores or discount shops.
- The expiration date is printed on the product box.
- This method isn’t foolproof, but expired tests often produce false positives.

Ask for a urine sample from someone who is pregnant. While a bit gross, this is a surefire way to get a positive result. Ask a pregnant friend to provide a urine sample in a sealed container. Take the sample into the bathroom to “test.”
- Be careful not to spill the urine on yourself.
- You can use the same sample to fake results multiple times.
Tips
- Don’t drag the joke out. Reveal the truth shortly after you’ve successfully tricked everyone.
- While a baby bump isn’t usually visible in the early months, you can arch your back slightly to make your stomach appear rounder.
Warnings
- Faking a pregnancy can damage people’s trust in you. Additionally, you might face consequences when others discover it was just a prank.
- Avoid forging medical documents, as this can be considered fraud, depending on how far you take the joke. It’s best to steer clear of legal trouble.
