Well, she is only a baby herself, so its not ideal as she is still growing, however i made a similar mistake to you and bought 2 young "females" from a pet shop, one turned out to be a boar so got him nuetered, the female was already pregnant, she had 3 babies, one of which sadly passed away but it looked deformed to be honest. Apart from that she had 2 other healthy babies and was fine herself.
Its more dangerous for a sow of a year or older to get pregnant as their pelvic bones fuse so therefore they cant give borth naturally.
How long have you had her? How has her weight been? Can you post a clearer pic of parts and a birdseye view so we can see what shape she is.
