How many days after ovulation will a HPT be positive? I ovulated 8 days ago.?

Question

I have been having odd cramps on my left side only for the past two days. Any thoughts?

Answer 1

If the egg is fertilized, it takes 8-10 days to travel to the uterus to be implanted. Then it takes about 2 days to produce enough hormones to be read on a home pregnancy test. So... at the earliest, 10 days after ovulation. But it is always best to wait until you've missed your period. That is when you will get the most accurate reading on a sensitive HTP.

Answer 2

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

in case you ovulated 4-6 days in the past you expected your era and are actually in simple terms 8 days previous due meaning your attempt 12-14 days after ovulation. you are able to desire to be testing too early. you are able to usually get a correct try result everywhere from 12 to sixteen days after ovulation. Wait some days and take a check out lower back. desire this enables! solid success **toddler airborne dirt and dust**

Answer 4

Well you usually have to be within a few days of starting your period. But odd cramps is common with early pregnancy because your uterus is beginning to stretch. Good luck.

Answer 5

the cramps could be from implantation, when the egg implants itself into the wall, as for the test you have to wait until 4 days of your pregnancy test, to get results earlier you would have to have a blood test from your doctor.
