Every woman is different and the amount of time it takes for the fertilized egg to implant in the uterus wall varies widely. Implantation will usually occur somewhere between 6 and 12 days past ovulation. Once the fertilized egg implants, the developing placenta begins releasing hCG (human chorionic gonadotropin) into the blood. Some hCG also gets passed into the urine. hCG levels usually double every 2-3 days in early pregnancy. Once the levels are high enough they can then be picked up by a home pregnancy test.
Pregnancy test sensitivity will be your next consideration. The sensitivity of home pregnancy tests vary quite widely from brand to brand - anywhere from 15 mIU to 250 mIU. The lower the level of hCG picked up by the test, the earlier you will see a positive result.
Remember many women get a negative test result before they get a positive, this is usually due to testing too early. To avoid unnecessary disappointment you should try and wait as long as possible before testing.
