Not sure if my pig is pregnant or not?

Question
Hi,
I have just rescued to females that were dumped. One of them seems to be a bit bigger in the abdomen area. I also noticed the other day her teets are longer than my other pioggies is this a sign of pregnany?  I am not sure exactly how pregant she is...even if she is? What are some other signs externally that i would notice if she is?
Thnk you  

Answer
Hi - are you absolutely sure they are both females? They could be pregnant. Unless you get an ultrasound at the vet, or x-ray, you'll just have to wait 60 days to see. They usually start showing at 6 weeks.

They could have recently had a litter too.
