Hello

Have you separated the father yet? If not, do so immediately as the female can get pregnant again as soon as she gives birth.

Do you have an exotics vet lined up in case of complications? Are you going to get the male neutered?

Welcome! Unfortunately, that's one of the biggest problems with buying from pet stores. I went through the same thing, they told me two girls, but they sold me a girl and a boy. Seperate the male immediately because the sow can get pregnant right after she gives birth. And it's always best to have a exotics vet number on hand in case of any complications. It might also be a good idea to bring in the pigs so the vet knows you and will recognize you if you have an emergency call.

Welcome to the forum. Like, the others said, separate the father now, as the mother can get pregnant again right after delivery. At three weeks old any male babies can go live with dad, so they don't get mom or sisters pregnant. Good luck! I can't wait to see baby pigtures.
