How many days after ovulating can I take pregnancy test please I'm excited to know?

1-2 weeks . Assuming you have regular cycles, a fertilized egg will take 5-7 days to implant. This is a pregnancy. Most urine pref tests cannot detect the implantation due to low hormone levels (hcg). It is possible, just not always predictable. Most tests are positive by the time of the missed period. In other words, most tests are pos earliest 1 week to, usually 2weeks, after fertilization.
