In the first few weeks after implantation hCG levels double every 48-72 hours. This means that the level of hCG in pregnant women goes from nearly nothing to a lot in just a few days time. At 7-10 days after ovulation, a pregnant womanâs hCG levels will be up to 50 mIU/ml. Find a pregnancy test that can detect a level as low as 25mIU/ml. You can begin to test at 7-10 days past ovulation.
Implantation is the process by which a fertilized ovum (egg) implants into the uterine wall to obtain oxygen and nutrients from the mother. This usually occurs between 6 and 8 days after conception. Conception itself can occur anywhere between a few hours and 5 days after intercourse.rom this point on, the embryo must travel down the fallopian tube to implant in the uterus. This can take about a week. Only after implantation can you tell whether or not you are pregnant. This is because after implantation, the part of the embryo that becomes the placenta begins producing a hormone called beta HCG.
