What Is It? Keloids are raised overgrowths of scar tissue that occur at the site of a skin injury. They occur where trauma, surgery, blisters, vaccinations, acne or body piercing have injured the skin. Less commonly, keloids may form in places where the skin has not had a visible injury. Keloids differ from normal mature scars in composition and size.
A: The earliest you can get a positive result on the most sensitive pregnancy tests is seven days after ovulation. Implantation needs to occur before hCG is produced, and that generally happens between 6-12 days post ovulation, usually by 10 days after.
And your body starts producing hCG only after a fertilized egg implants in the uterus. If it's very early in your pregnancy, your body might not have produced enough hCG yet. In that case, you'd get a negative result at first. Also, some tests are more sensitive than others, and no test is 100 percent accurate. And a few women have such low levels of hCG during pregnancy that home tests can't measure it.
