In brief: Hard to be accurate

A pregnancy test will usually turn positive somewhere around 4 weeks (2 weeks after conception).
So you probably weren't 4 weeks on 8/7, but became 4 weeks sometime between 8/7 and 8/16. So you're likely around 4-5 weeks. An ultrasound at 6+ weeks will give you a better idea.
