How Early Can I Take a Pregnancy Test?

How Soon Can I Take A Pregnancy Test? 

...and other Top FAQs

It's probably one of the most-asked questions we receive here by email. Everyone wants to know: "How soon can I take a pregnancy test?" Of course, there are a number of variations on this question, particularly for women who are fertility charting and who want to know - exactly - at how many days past ovulation they can begin testing (and hopefully get that earliest positive result). Below, we'll look at all the facts and details relating to answering this question - and give you the most informed framework for hazarding a "best guess" on when you can begin!

Question: When Can I Take A Pregnancy Test? And the answer is.... that depends! Yes, as with all good questions, there is never a good, easy, simple one size-fits all answer. But we will be happy to provide you with all the variables involved in answering this question for yourself, and hopefully this can give a relatively good picture for a time frame for testing.

The Variables Involved in Pregnancy Testing:

1. The HCG Sensitivity of a Given Test (high sensitivity pregnancy tests are able to detect pregnancy sooner than "regular" pregnancy tests)

2. The Rate of hCG Production

3. Urine Dilution / Consumption of Liquids

4. What Time of Day You Test

5. Do You Know When You Ovulated? (Ovulation tests or a fertility monitor should be used to help determine this.)

6. Actual moment of "Implantation"

Let's begin with some background info. A pregnancy test functions by homing in on one specific reproductive hormone that starts flowing through your body the moment you become pregnant. This is not the moment of conception, however. Conception is when a sperm and egg unite (aka fertilization). The fact is that a pregnancy is "inaugurated" not at the moment of fertilization, but when a fertilized egg actually "hooks up" to your womb. That is the moment you are pregnant, and the time that this unique hormone (hCG) is able to flow from the placental tissue into the bloodstream of the mother. From the blood, the hCG circulates through the body and ends up in the urine as well.

Ovulation and Implantation: Now, here's the confusing part that makes answering this big question of "When Can I Take a Test" a bit difficult. Once the egg is fertilized, it floats around for a few days - even up to a week or so - before it is able to nestle its way into a comfortable home in the uterine lining (or wall of the womb). Theoretically, if you ovulate on Cycle Day 14, and you "conceive" on day 14 or 15, the embryo will just be hanging around looking for that special place to snuggle up into the womb. It's possible that your implantation date can take place just a handful of days after conception. But it's also possible that it can take up to a week or more! Thus, it is not possible to pinpoint a specific day when you can test and get that long-sought-for positive result. However, if you know when you ovulate (thanks to ovulation tests) you can still better focus in on a pregnancy test start date.

hCG Levels: The next crazy variable to confound us in seeking an answer to the big question is how fast hCG increases in your system. The fact is, different embryos will produce hCG at a faster or slower pace, depending on the woman and where the embryo implants. This means that for some women, hCG levels will rocket and for others it may trickle a bit at first. The good news here is that the amount of hCG in your body will increase rapidly - and double almost daily. This is called the doubling rule, the exponential increase of the hormone, and it means that even if hCG production is lower for some women, it won't take too much longer for the amount to reach the threshold required for a pregnancy test to detect the presence of the hormone in blood or urine.

Test Sensitivity: The next variable can be controlled when you purchase a test. In the past, most tests had lower sensitivity thresholds, meaning that they required you to wait at least until your missed period to begin taking a test. Many tests still ask you to do so. However, newer FDA-Approved products do allow you to test before your missed period, including certain drugstore tests like First Response and affordable, high-sensitivity test kits available online. The highest (reasonable) threshold is 20mIU/ml/hCG. This means that the amount of hCG in a given urine sample must exceed this "trigger" level for a positive test line to be produced. So, using higher sensitivity tests, the answer to the big question is: You may begin testing at around seven to ten days past ovulation. But wait!!! As noted above, variables like implantation date and rate of hormone production do not guarantee a positive result during this early testing window. According to research data, it's likely that you may first see a positive pregnancy test during this time, but a negative result is still possible and does not close out the possibility of pregnancy. It's wise and recommended to conduct follow up tests!

FMU and Hold Time: Okay, so we now have a kind of fuzzy time-frame for knowing when to start taking a pregnancy test. At this point, we can look at other variables to help ensure that we can increase the accuracy of the result. These are factors we can control simply by following the directions in the instructional insert and taking certain steps to ensure that the hCG in a given urine sample will be at its highest levels. If you have been around this website, then you already know that testing with First Morning Urine is the first big factor in getting the earliest positive test result. First morning urine will exhibit a higher concentration of the hormone than samples collected at other times of the day. That's because all night, while you have slept, hCG has been allowed to accumulate in your urine. Now, if you do end up testing during other times of day, there are some things you can do to increase result accuracy. First, in the hours before you "pee for a test", try to avoid flushing the body with a lot of liquids. Never dehydrate yourself! Just take it easy on the liquids and hold your urine as long as possible before you collect a sample or pee on that stick.

If you are trying to conceive and are fertility charting, then you will know the approximate date of ovulation. With that fact, you can pretty much determine the approximate days for when you can take a pregnancy test. Best of luck and babydust to all!

My names are joan jane am from USA i want to use this
opportunity to thank my great doctor who really made my life a
pleasurable one today. This great Doctor brought my husband back to
me, i had 3 lovely kids for my husband, about 3 years ago i and my
husband has been into one quarrel or the other until he finally left
me for one lady. i felt my life was over and my kids thought then
will never see their father again. i tried to be strong just for the
kids but i couldn't control the pains that torments my heart, my
heart was filled with sorrows and pains because i was really in love
with my husband. Every day and night i think of him and i always wish he
will come back to me, until one day i met a good friend of mine that
was also in a situation like me but her problem was her ex-boyfriend
who she had an unwanted pregnancy for and he refused to take
responsibility and dumped her. she told me that mine was a small case
and that i shouldn't worry about it at all so i asked her what was the
solution to my problems and she gave me this great man phone number
and his email address. i was doubting if this man was the solution, so i
contacted this great man and he told me what to do and i deed them
all, he told me to wait for just seven days and that my husband will come
crawling on his kneels just for forgiveness so i faithfully deed what
this great man asked me to do and for sure after four days i heard a
knock on the door, in a great surprise i saw him on his kneels and i
was speechless, when he saw me, all he did was crying and asking me
for forgiveness, from that day, all the pains and sorrows in my heart
flew away,since then i and my husband and our lovely kids are
happy.that is why i want to say a big thanks to Doctor okogie. This
great man made me to understand that there is know problem on earth that

My name is Felicia Roland, from ITALY I never believed in

love spells or magic until I met this spell caster once

when I went to Africa in February this year on a business

summit. I meant a man who’s name is Dr Isaac he is

really powerful and could help cast spells to bring back

one’s gone, lost, misbehaving lover and magic money spell

or spell for a good job or luck spell.I’m now happy & a

living testimony because the man I had wanted to marry

left me 3 weeks before our wedding and my life was upside

down because our relationship has been on for 6years. I

really loved him, but his mother was against us and he had

no good paying job. So when I met this spell caster, I

told him what happened and explained the situation of

things to him. At first I was undecided, skeptical and

doubtful, but I just gave it a try. And in 7 days when I

returned to Italy, my boyfriend (now husband) called me by

himself and came to me apologizing that everything had

been settled with his mom and family and he got a new job

interview so we should get married. I didn’t believe it

because the spell caster only asked for my name and my

boyfriends name and all I wanted him to do. Well we are

happily married now and we are expecting our little kid,

and my husband also got the new job and our lives became

much better. His email is drisaachelpcenter@gmail.com
