Just a WAG, but say at the end of the movie, Hank, Scott and Hope all travel into the Quantum Realm to try to rescue Janet Van Dyne. It takes months of relative time on the outside world but only minutes or hours for them. They find her and either bring her out with them or Hank decides to stay there with her (if it's something idyllic and not a hellacious limbo). I'm leaning towards her staying there, maybe with Hank. But while they're there, they find Carol Danvers, who's been trapped there since the 1990s and the events of the Captain Marvel movie and they take her out with them. When they emerge, it's into the world created by Infinity War, thus setting the stage for Avengers 4.
Just my wild-ass guess as I said.
