how long after ov can a blood test pick up hcg read somewhere it was 72 hour so is that 3dpo????

I don't know for sure, but I've heard the same thing, it's probably 3dpo

thanks monique x

I've googled it and gettings answers like 6-12 days, must be longer than I thought.

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.
