It depends on when you ovulated. Not everyone ovulates mid-cycle. And not everyone gets their period 14 days after they ovulate. Your luteal phase is the time from when you ovulate to when your period starts and that can be 12 days, 15 days, sometimes even 18 days depending on how long your cycle is. So it is possible for you to be pregnant if you ovulated around the time you had sex.
How long are your cycles usually? You ovulate mid cycle, and then would get your period 14 days after you ovulate. By July 2 you would have probably missed ovulation, so you wouldn't have been in your most fertile time to conceive. Has this months arrived, or is it late? If it's late you can take a test with first morning urine, but judging by when you had sex, I think it's unlikely.
