14 days after , should i be getting positive pregnancy tests by now?

it has been 14 days today since we had , were TTC. Should i be getting a BFP by now if i was in fact pregnant? i heard that some ladies didn't get positives until they were a few weeks late, is that true? anyone experience that? or how many DPO did you get your positive. IF i ovulated like my online calendar said then i would be 10 DPO today. Should i have a BFP at 10 DPO?
