When did Hera get pregnant?

Can you elaborate on the context surrounding the question, "When did Hera get pregnant?"? Are we referring to Hera, the goddess in Greek mythology, or is there another Hera in a different context? If we're talking about the Greek goddess, Hera's pregnancy is often tied to her jealousy and rivalry with Zeus' other consorts, particularly Hera's sister Demeter and the mortal woman Semele. In some myths, Hera's pregnancy was a result of Zeus' trickery, while in others, it was a direct result of their union. Could you please provide more information or clarify the question to help me give a more accurate answer?
