Sperm met egg last week, and voila—you've made a baby! It's so early that when you're 3 weeks pregnant, you may have no idea that you're actually pregnant. Conception just happened a few days ago, and there probably hasn't been time for you to miss a period yet at week 3 of pregnancy.

The same pregnancy hormones that gave you that positive pregnancy test can also cause some of the more typical 4-week pregnancy symptoms. These hormone levels increase pretty quickly, so while it's normal to be 4 weeks pregnant with no symptoms, brace yourself: nausea and vomiting may be in your near future.

Depending on when you conceived, a positive test is possible as soon as three to four days after implantation. However, because this hormone increases as the baby grows, it's best to wait until after day one of a missed period to do a test (7).

The tests only turn positive once there is a certain level of the hCG hormone present in your urine: if you test too early, the result might be negative even though you are pregnant. Therefore, if you don't get your period but you had a negative result, test again after two to three days.

Since it can detect pregnancy as early as 6 days after ovulation, you could be able to confirm your pregnancy at/around 3 weeks. The downfall is that most doctors will not order a blood test this early to determine pregnancy unless there is a medical reason to do so.

Hormones and pregnancy symptoms HCG levels also provide the basis for detecting a pregnancy with a pregnancy test. This is why early pregnancy signs do not become noticeable until around the time the woman's next period would have been due - or 12 to 14 days after the moment of fertilisation.

Also, if a woman has recently given birth the hCG hormone typically remains in her body until 3-4 weeks after giving birth. So the only way to confirm if you are actually pregnant after having received a positive test result on a pregnancy test is through ultrasound.
