With a period STARTING on June 22 you'd normally be expected to ovulate between days 11-16 of your cycle or July 3 and July 8.
The egg is only viable for up to about 48 hours max. So by July 10 it wouldn't likely be capable of being fertilized.
Odds are VERY GOOD that you were already pregnant when you had the one night stand.
Your boyfriend (a) is VERY likely the father.
Based on your post, 95% or greater. A DNA test can verify and it can be done now, non-invasively. Google "non invasive dna test."
