Implantation occurs on average, 9 days after ovulation (with a range of 6-12 days) or about 5 days before a missed period. hCG levels are detected in the blood as early as 2-3 days, and in the urine 3-4 days, after implantation.

A pregnancy test should be taken whenever a woman suspects she may be pregnant. 3﻿ Since it can take up to a week for hCG levels to rise, it is best to wait a good 7 days or so after a missed period to take a home pregnancy test.

HCG Levels During Pregnancy HCG levels rise eight days after ovulation, peak at 60 to 90 days, and then lower slightly, leveling off for the remainder of the pregnancy. Typically, during the first 10 weeks of your pregnancy, HCG levels double every two days.

A woman's body begins to produce hCG from cells in the developing placenta (tissue that nourishes a growing fetus) soon after implantation of a fertilized egg inside the uterus. Around eight days after ovulation, trace levels of hCG can be detected from an early pregnancy.

This typically takes seven to 12 days after successful implantation of an egg. You may receive an inaccurate result if the test is taken too early in your cycle. Here are some signs that you should take a pregnancy test.

You tested too early: The hCG levels in your urine might not have risen enough to be detected in your urine yet. Ideally, you should wait about seven days after a missed period to do a test. This way the levels of hCG will have increased and that much waited for “you're pregnant” indicator will be there.

They're miscalculating when they ovulated. This is most likely the case for anyone who claims to get a positive test at 7 DPO or earlier. It can take up to two days for hCG to build up to detectable levels, but it can happen sooner for some women. This could explain positive pregnancy tests as early as 8 – 10 DPO.

Are early pregnancy tests as accurate? The hormone hCG is manufactured by the placenta and first appears in your urine anywhere from 10 to 14 days after fertilization. But while hCG increases rapidly in the first few weeks, not everyone produces the exact same amount on the exact same timeline.

It takes a couple of days after implantation to have enough hcg for a positive pregnancy test. Good luck.

Timing of implantation Detection of hCG depends on the timing of implantation, so hCG can normally be detected in the blood between nine and 16 days after ovulation. Urine hCG can be detected about two to three days after blood hCG can first be seen.

But with regular laboratory hCG tests, hCG is usually found in sufficient levels as early as 2-3 days after implantation. Implantation happens as early as 6 days after ovulation/fertilization (usually about 9 days after ovulation), so blood hCG can be found as early as 8-9 days after ovulation/fertilization.

If the embryo does in fact implant and begin to grow, hCG levels will rise and the line should get darker." hCG levels are abundantly present two to three days after your missed period (15 to 16 days after ovulation), so if you have a faint line, wait until after your missed period to test.
