Get a false positive test online

Well, the easiest thing to do is get a false positive test online. You can open the test and pretend to pee, and then show it to your partner. This way he will email believe that you are pregnant. You can buy these tests online, or at a local shop. 

Dip the pregnancy kit in a can of soda 

Some ingredients used in the making of sodas like Pepsi or Coke are similar to the pregnancy hormones. Take a can of Pepsi and dip the pregnancy stick into it. This will have the same chemical reactions as that of urine with HGC hormones. Therefore, this can give you a false positive as you needed. 

Use a pen to draw two lines on the test 

All you need to do is, get a pink pen, similar to the color of lines. Open the kit and draw the two lines, which means the test is positive. Next, dab some water onto the test to make it look like you peed on it. This can be the easiest way to get a false positive test. 

Try an expired pregnancy test 

Using an expired test, will certainly not give you the right result. Peeing on an expired pregnancy test may increase the chances of getting a false positive. Although it may be difficult to find an expired pregnancy test. You may look for it online, or ask your friends if they have any. 

Let the test sit too long before looking 

Most pregnancy tests are accurate for a certain time frame. If you take a standard pregnancy test, the results may be true for the given timeframe. Once the urine starts to evaporate from the pad, the line may start to get darker and it may look that it is a positive test. 

3 ways to trick a pregnancy test into false negative 

  • Taking the test too early 
  • Using diluted urine 
  • Using the test incorrectly 

However, it is also possible that you are looking for ways to trick a pregnancy test into a false negative. You may want to prove to your parents that you are not pregnant before getting an abortion done, you may not want your husband to know that you are pregnant in the first place. Hence in such situations, there are three things you can do. 

Take the test too early. 

If you take the test earlier after missed periods, the harder it is to detect the HGC in your body.   the pregnancy hormone human chorionic gonadotropin is present in your urine at all times. however , it is detectable only after you have missed your period for the first time. Taking the test right after you have missed your period, you would not have conceived the baby. 

Using diluted urine 

Urine is the source of at-home pregnancy tests, your urine contains what is called a pregnancy hormone HGC. if you mix water in your urine, there are chances that the level of HGC will decrease too. This will lead to a false negative. 

Using the test incorrectly 

It is very important, to follow the instructions written on the pregnancy test. If they are not followed properly, say, for example, if you do not pee on it rightly or, wait for way too long to look at the results, you may get a false negative. 

What is a pregnancy test? 

Well, in simple terms, a pregnancy test tells you if you are pregnant or not. But the question is how? At-home pregnancy test, check for the availability of the hormone-  human chorionic gonadotropin. This hormone is released in humans when the fertilized egg attaches to the uterine lining and forms the placenta. A blood test can detect the HGC about 11 days after the conception, while a urine test takes 12-14 days after the conception. 

It is seen that the HGC levels increase every 72 hours until 8-11 weeks of pregnancy, and decrease gradually after the delivery of the infant. 

How does a pregnancy test work? 

Urine is the source that works on a pregnancy test. The urine is used to detect the HGC level in the human body. If the body contains high levels of HGC, it triggers the chemical reaction and the test shows positive. If there is a lack of HGC hormone in the body, the test shows negative. 

It is usually recommended that you take the test with the first pee in the morning as this might contain the most amount of HGC.To take the test, you can either pee directly in the stick, or dip the stick in a box of collected urine. Let the stick settle for two minutes and look. If the pregnancy stick shows a single line it is negative, which means you are not pregnant. But if the stick has two lines, it means it is a positive test. Congratulations you are pregnant. 

For detailed instructions, read the instruction paper that comes along with the pregnancy test. Follow the instructions properly, to gain an accurate result. 

How to fake a pregnancy? 

If you are planning to play a prank on your husband or boyfriend by showing them a false positive test using the above-mentioned ways, you may also want your prank to look true. You can do this by faking a few early symptoms of pregnancy. Although make sure you play the prank safely without hurting yourself or your husband/ boyfriend’s feelings. 

Complain about missing your period.

What better scare than the scare of missing periods. If you plan on playing a prank, start with complaining that you have missed your periods. Tell them that you are worried about missing your periods and concerned with the reason. 

Pretend to have morning sickness

Morning symptom is the most famous symptom of pregnancy. If you want your prank to look believable, pretend to have morning sickness. Randomly, excuse yourself and run to the washroom and let the water run, while you pretend to vomit. Tell them that you are nauseated and do not feel like eating anything 

Act like your breasts are tender 

Tender and swollen breasts are a common symptom of pregnancy due to extreme hormonal fluctuation. Complain that your breasts are hurting and tender. Put a warm compressor over your chest to ease your pain. 

Visit the washroom frequently 

Urinating more than usual is another early symptom of pregnancy. Go to the restroom more than usual, and pretend to urinate. If your partner has not noticed, go to them and tell them your concern about it. 

Pretend to feel tired all the time 

On a Sunday, when you have done nothing, tell your partner that you are extremely tired. Over the week, tell him that you are tired more than regular and want to just sleep. Fatigue is a very common problem during pregnancy due to hormonal imbalance. Complaining about tiredness for no reason whatsoever will certainly worry your partner. 

Pretend to have mood swings 

Well, this will be the easiest. Get emotional at everything. Because pregnancy causes so many hormonal fluctuations, it often causes mood swings. You can cry at small commercials, or after a sad meme. Tell him you are feeling sad for no reason and show fluctuations in the mood. 

Pretend to have cravings 

After you come home from work every day, ask your boyfriend to fulfill your different cravings. Ask him to take you to the ice cream parlor, or to a restaurant that serves the best past. Tell him you are dying to eat that one particular thing. 

The faking of these early symptoms of pregnancy will make your prank more believable. Your partner will notice the symptoms of pregnancy and believe that you might be pregnant.
