For most women who’ve been waiting to become pregnant, an early pregnancy test is crucial to ascertain whether they’ll test positive or not. The answer to the question of whether or not you’re pregnant is quite a revelation and the feeling can’t be described in words.
Frequent tests could get costly and disappointing, especially if they’re negative each time. So when’s the right time to take an early pregnancy test with the least expense and disappointment?
Let’s find out how they work and just how body alterations take place in an individual at the beginning of pregnancy.
How Do Pregnancy Tests Work?
Home Pregnancy Tests have been around for many years now and are easy to pick up from local chemists and supermarkets. They can vary in price from cheap to expensive; you may even be able to pick up free pregnancy tests from your local medical centre.
Pregnancy tests work by taking samples of urine to identify the existence of a pregnancy hormone hCG (Beta Human Chorionic Gonadotropin).
The body begins to create hCG whenever a fertilised egg embeds itself inside the uterus and is transmitted through the cells that will go on to form the infant’s placenta. It may usually be traced in the urine from about 6 to 14 days after fertilisation.
The best thing to do is to wait until a period has been missed and tell-tale signs of pregnancy show up prior to testing. In such a case, an early pregnancy test would provide a confirmation of what was felt by you in the first place.
But then women looking to conceive may usually be in a tearing hurry to take an early pregnancy test and may be ready to do so right after having sex!
The accuracy of an early pregnancy test can easily be doubted. Fertilisation of the egg through sperm may take 5 days if sexual intercourse occurs at the right time. There is a right time for it because fertilisation may not be possible once the egg starts to disintegrate 24 hours subsequent to ovulation.
About 5 to 7 days after ovulation has occurred, the egg is implanted in the lining of the uterus after travelling down the fallopian tube. You must wait for an increase in hormonal levels in order for it to be detected correctly. Also remember not to consume too much water when you’re going to get a test conducted because it can show a lower count of hCG in your urine sample. hCG is a pregnancy hormone that doubles itself every 48 to 72 hours. In fact, you should test for it every second day.
The earliest that you can test is 7 days past ovulation because the implantation wouldn’t have occurred any sooner than that. The medical terminology for it is 7 Days Past Ovulation or 7 DPO in short. Even 7 DPO may be early — it could be the right time only if you’re sure about the day when the ovulation took place. Getting a test done between 9 and 10 DPO is also quite optimistic, although it comes within the “5 days before your missed period” duration. In fact, many women test later than that.
12 to 14 DPO is the best time to go for a pregnancy test. Alternatively, it could be just before your period begins. At this time, the egg is well implanted and hormones have been produced as needed, which will then show a positive test result.
In the event of having an ectopic pregnancy, a situation where the pregnancy has occurred outside the womb, the hormonal levels may not show a positive result. Some women wait until 15 to 18 DPO before they take a test or at least until some time has elapsed. There are cases where women don’t take a test until several days later.
Are All Pregnancy Tests the Same?
Pregnancy tests vary in the degree of sensitivity. A truly sensitive test will show a positive result after detecting even a small level of hCG. mIU/ml or milli-international units per millilitre is the terminology that’s used to report the level of hCG. A level of 20 mIU/ml is more sensitive than tests with 50 mIU/ml.
How to Improve Your Chances of an Accurate Early Test
Want to boost your odds of getting an accurate result? Here are some tips:
First off, track your cycle religiously. Knowing exactly when you ovulated gives you a much better idea of when to test. Apps can help, but good old-fashioned calendar tracking works too.
Next, spring for the fancy tests. They’re pricier, sure, but they’re often more sensitive. Look for ones that can detect hCG levels as low as 10 mIU/ml.
Timing is everything. Take the test first thing in the morning when your urine is most concentrated. And for heaven’s sake, don’t chug a gallon of water beforehand!
Lastly, be patient. It’s tempting to test every day, but that’s a recipe for frustration (and an empty wallet). Wait at least a day between tests to give those hormone levels a chance to rise.
Remember, even the best tests can give false negatives early on. If you get a negative but still feel pregnant, wait a few days and try again.
Understanding False Negatives and Next Steps
False negatives can be emotionally challenging for women trying to conceive. If you receive a negative result but suspect you might be pregnant, don’t lose hope. Hormone levels vary widely between individuals, and some women’s bodies take longer to produce detectable amounts of hCG.
Consider these follow-up strategies:
- Repeat the test in 48-72 hours
- Use first-morning urine for highest hormone concentration
- Choose a more sensitive test with lower hCG detection thresholds
- Consult your healthcare provider if uncertainty persists
Remember, patience and persistence are key when navigating early pregnancy detection.
Will the Tests Be Accurate?
The tests will be accurate provided you follow the instructions. Be aware that you’ll test a false positive if it’s too early since not enough hormones would have been produced in the body. Hence you should wait for at least 4 to 5 days before testing again. Though rare, it’s also possible that even if the test shows you as being pregnant it could be a case of being false positive. Medicines containing hCG may influence the test results.
