late delivery of piglets

Question
We have two sows pregnant, both we believe conceived the same day.  One sow has had 7 piglets (2nd litter).  The other sow still has not had her piglets.  I'd say about a week late now.  She is obviosly pregnant, yet not appearing grumpy or uncomfortable.  Is it possible to be long over due?  Suggestions

Answer
Hello Kathleen,
I want to start off by saying that I am not a Veterinarian.
I can only give you an answer based on my experience.
Pot Bellied Pigs gestation is 3 months, 3 weeks and three days.
The problem is that you can't be sure she was bred on the same day as your other sow or if she is even pregnant for sure.
I would advise you to talk to your Veterinarian and get his or her advise.
