?
For many women, deciding when to take a pregnancy test is one more additional source of anxiety as the two-week wait ends. There is the part of you that is dying to know if this month will be the month you finally get pregnant, and the temptation to take a pregnancy test before your period is late is oh-so tempting.

On the other hand, you are most likely aware that taking the test early may come up negative, even if you are pregnant.
Understand How Pregnancy Tests Work
Before you decide when to take a pregnancy test, it helps to understand how they work. The tests detect pregnancy hormone, human chorionic gonadotropin (hCG), in your urine. Some tests also detect a variation of this hormone, known as hyperglycosylated hCG (H-hCG).
The regular hCG is produced only after an embryo implants in to the endometrium, while H-hCG begins to be released earlier, some time after fertilization.
Levels of Pregnancy Hormones and Pregnancy Tests
When pregnancy tests tell you how much hormone they detect, they usually tell you how much hCG the test requires. A woman's level of H-hCG, though, is typically higher than hCG. The majority of pregnancy tests are not sensitive to the hormone H-hCG.
If a pregnancy test does detect H-hCG, you're more likely to get a positive result early. If a pregnancy test is not sensitive to H-hCG, and only detects regular hCG, getting an early positive result is less likely.
The great majority of pregnancy tests on the market, unfortunately, are not great at detecting H-hCG.
Understanding How Early Result Pregnancy Tests Work
What about early results tests, though, the ones that promise results three or four days before your missed period?
It's important to know that these tests assume a 14-day luteal phase. (That's the time between ovulation and when you get your period.) If your luteal phase is usually 12 days, four days before your missed period would be 9 days after ovulation. Way too early to test.
If you have a luteal phase of 15 days, though, 4 days before your missed period is 12 days after ovulation. You still may not have enough hormone that early, but you've got a much better chance than someone with a shorter luteal phase.
Why would I need a blood pregnancy test?:
This is the type of pregnancy test that uses blood to detect hCG. This can give your doctor or midwife specific numbers to measure and compare. In general, your hCG will nearly double about every two days in early pregnancy. So by having multiple blood tests about 48 hours a part, you can track this hCG number and get a better read on the pregnancy. Serial blood tests can help your practitioner monitor your pregnancy for miscarriage or even an ectopic pregnancy or multiples.
What do I do if my pregnancy test is positive?:
If you have a positive test you can assume that you are pregnant. Congratulations! You will first want to decide with whom you will share the good news. Will you think of a fun way to tell your family? Have you chosen a midwife or a doctor? There is a lot to do and we'll help you!
