I am a first timer on PB pigs. People say they have saggy bellies but she seems preggers 2 me. I see pointy teats but no milk pouch yet. Please experts help here... how sure can I be she's in fact pregnant. She was with a much younger male for a couple months (he was 5 months old). I have not seen her nest or carry hay and does not even use her nesting area... however looks pretty round to me. I appreciate your assessment. Thanks.
