Transforming Couple

When I wake up, my wife becomes my husband and my husband becomes my wife. This is so embarrassing! The worst thing is that the "wife" at this time is pregnant! There is no other way, the two people can only replace each other and start a "cospaly" life of identity swapping that doesn't know when it will end. In the end, the wife seems to have gradually found herself again, and can the husband successfully "give birth" to the baby? Where should this couple go...
