Luckily for all involved they surrendered! It was another 6 months before the next A-Bomb was ready... Actually, that isn't true. The first bomb, Fat Man, was made with uranium-235, a rare isotope which was extremely difficult to separate from the more common uranium-238. The bomb design was simple, and we were fairly certain it would work, so it was never tested before it was dropped on Hiroshima. Had that been our only design, it would have taken several months to enrich enough bomb-grade uranium to build another.
However, the second bomb, Little Boy, was a completely different design. It used plutonium-239 which could be produced in large quantities by bombarding common uranium-238 with slow neutrons. The design was much more complicated, though, so they tested it before they dropped one on Nagasaki.
Had the war continued, we could have produced about one plutonium bomb per week. Fortunately, though, we didn`t have to.
