when to test during implantation
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 womanâs 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.
