Usually you can expect a positive test sometime around 2 weeks past ovulation. If you don't get it right away you can try again a few days later, so pretty much expect a positive test if you are pregnant when your period would start.
As far as implantation bleeding, you might have it, you might not. I had it with my first pregnancy 14 DPO. I didn't have it at all with my other two pregnancies.
