How soon after a missed period can I take a home pregnancy test and get accurate results?
Many home pregnancy tests (HPTs) claim to be 99% accurate on the day you miss your period. But research suggests that most HPTs do not consistently spot pregnancy that early. And when they do, the results are often so faint they are misunderstood. If you can wait one week after your missed period, most home pregnancy tests will give you an accurate answer. Ask your doctor for a more sensitive test if you need to know earlier.
When a home pregnancy test will give an accurate result depends on many things. These include:
How long it takes for the fertilized egg to implant in the uterus after ovulation. Pregnancy tests look for the hormone human chorionic gonadotropin (hCG) that is only produced once the fertilized egg has implanted in the uterine wall. In most cases, this happens about 6 days after conception. But studies show that in up to 10 percent of women, the embryo doesn't implant until much later, after the first day of the missed period. So, home pregnancy tests will be accurate as soon as one day after a missed period for some women but not for others.
How you use them - Be sure to follow the directions and check the expiration date.
When you use them - The amount of hCG in a pregnant woman's urine increases with time. So, the earlier after a missed period you take a HPT, the harder it is to spot the hCG. If you wait one week after a missed period to test, you are more apt to have an accurate result. Also, testing your urine first thing in the morning may boost the accuracy.
Who uses them - The amount of hCG in the urine at different points in early pregnancy is different for every woman. So, some women will have accurate results on the day of the missed period while others will need to wait longer.
The brand of test - Some home pregnancy tests are more sensitive than others. So, some tests are better than others at spotting hCG early on.
I got a negative result on a home pregnancy test. Might I still be pregnant?
Yes. So, most HPTs suggest women take the test again in a few days or a week.
Every woman ovulates at different times in her menstrual cycle. Plus, embryos implant in the uterus at different times. So, the accuracy of HPT results varies from woman to woman. Other things can also affect the accuracy.
Sometimes women get false negative results (when the test says you are not pregnant and you are) when they test too early in the pregnancy. Other times, problems with the pregnancy can affect the amount of hCG in the urine.
If your HPT is negative, test yourself again in a few days or 1 week. If you keep getting a negative result but think you are pregnant, talk with your doctor right away.

The newer test can tell as soon as 1 day after a missed period. 10 days late and negative tests should mean you are not pregnant. Stress can cause you to be late.

It's possible, but most at home tests would have showed a positive by now. Are you under a lot of stress, doing a lot of exercise, or not eating well? Any of those could make your period stop. If not you might want to consider going to a doctor for a blood test.

Its possible, its very common to get a false negative then a false positive, Me personally I had very low HGC levels during my sons pregnancy, I was 9 weeks and still got a negative home pregnancy test result, But you should be able to get a blood test done and hopefully it will show up on that, I had to be 9 weeks before it showed up I had many tests done during the first 9 weeks that all came back negative. So its possible, it all depends on the baby because with my daughter it showed up at only 4 weeks so see your GP and hopefully you'll get some good Christmas news. Good luck

There is a slim chance that you could be pregnant. I would go to the doctor and see what's up with your period being late. Stress can make your period late and so can some stds. not to scare you or nothing. Just go to your dr.

You're probably not pregnant. Most test will be positive a few days before your period is even due.
