Hello,
A pregnancy can be detected as early as 8 days after ovulation. HPTs differ in sensitivity; however, the two best (First Response Early Result and Clearblue Easy Earliest Results) can detect a pregnancy at the time of the missed menses (generally ~two weeks after conception). If negative, repeat in one week (and/or pay a visit to your ob/gyn).
Best regards,

well today is now 13-14 DPO and still nothing no signs of AF and no + HPT....I'm confused.
