Pregnancy test.?

Question

Is it okay to take a pregnancy test three days after you've had sex? I mean, I know it's okay. But do you know how accurate it is?

I plan to take another one in a month but I'm curious to know now.

Answer 1

unless you were previously pregnant from last month or so, there is no way it will be able to tell you now. At least not a home pregnancy test. However, a blood test can determine within 3-5 days. It sounds like you really want this I know but try and be patient. It will happen, and congrats if you are and if not then have fun trying some more!

Answer 2

A blood test will show you are pregnant 7 days after conception.

How soon can I test? Well, first you gotta know how the test works. Briefly: the home pregnancy test (HPT) works by detecting a hormone called human chorionic gonadotropin (hCG.) When an egg is fertilized, it takes about 6 to 12 days to implant in the uterus, and then it begins to secrete hCG. It takes another day or two for enough hCG to build up and make its way into your pee. So, generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation ("DPO") and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common. In my experience, if you use a sensitive "early" test (anything that detects 25 mIU/mL of hCG or less) you can test around 12-14 DPO and feel reasonably secure with your results (the later you test, the more secure you can feel in its accuracy.)

If you do not chart or monitor your fertility in any way, and you think you may have conceived, you should wait 19 days (or longer) after having sex to test. Why 19?! Sperm can live approximately 5 days in the proper environment; if the sperm managed to live until you popped an egg, the actual conception could have taken place several days after the sex act that got the sperm there. To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then. Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.)

Note: some HPT's say "test 5 days before your period is due!" or some such thing. Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14. "5 days before your period is due" thus really "translates" to 10 DPO.

Essentially, you should remember that your high school biology textbook was WRONG. NOT all women have 28-day cycles and NOT all women ovulate on Day 14. For more info on this type of thing, see the Fertility Info section.

Here's an example. This is the textbook-perfect 28-day cycle with ovulation occurring on day 14 (in pink.) 10 DPO and later are reasonable days for testing (in green.) This is the cycle the HPT companies have in mind when they say "test 5 days before your period is due!"



Well, not everyone's body works this way. Here's another 28-day cycle-- but this one has ovulation occurring a little bit later, still well within the normal range. Watch what happens to your (green) testing opportunities!



All of a sudden, "5 days before your period is due!" is way too early for you to expect a positive test! (I tend to ovulate later myself, so by the time the "gold standard" of testing at 14 DPO is applicable, my period is already 3 days late! I needed to use an "early detection" test on the first day of my missed period. A "regular" test would probably have been negative-- even though my daughter is living proof that I was, indeed, pregnant ;)

Of course, it works in reverse, too. If you're an early ovulator, you're lucky! Check it out:



In this scenario, you could test even sooner than 5 days before your expected period.

Ultimately, it's important to remember that implantation is a variable thing. You may be able to detect a pregnancy very early on, but then again, you may not! If you can't, don't despair.

Answer 3

The soonest you can find out is 5 days before your missed period. So if you had sex yesterday, but your period isn't due for another two weeks, try at the end of next week. This only works for First Response pregnancy tests as far as I know. Read the labels and talk to your pharmacist or better yet, your ob/gyn. ;)

Answer 4

You cantake one the day you have sex it is you who have to know if you want to waste the money
accurate, I can tell you that it will not be able to tell you if you have gotten preg from the sex you have 3 day ago
so if you truly want accuracy it is best to just wait
Good Luck

Answer 5

You would be wasting your money. I don't think there are any tests that can detect pregnancy sooner than two weeks after conception.

Answer 6

It depends on when ur supposed to start ur period. I think most of them are supposed to be able to dectect the pregnancy hormone like 3 days before ur missed period.

Answer 7

you really wont find out anything right away,the best thing to do if you are having sex is to use protection and this type of situation wont come up

Answer 8

no wait a little longer
