Hiya i think it takes about 7 days for the egg to implant and can take another 5-7 days for enough hcg to be produced to be detected but I guess it differs from woman to woman - I had two dates in mind which I think I may have ovd on so i got my very faint BFP either about 15DPO if I ovd when I first thought or only about 8 or 9 DPO if I ovd on the later date.
