POT BELLY PIG QUESTIONS?

I know this isn't the app for it, so I truly apologize.  I've done so much research but I'm still worried and don't know what to do. My pot belly pig is currently in labor. She had two piglets about 4  hours ago which were dead. We thought she was done but she has been laying on her side the entire time and you can tell she's still having contractions and she's trying to push but no piglets are coming out. Saw online that the duration of labor for a pig is 3 hours. And it's not been more than 3 hours.  I think one of her piglets might be stuck and I have no idea what to do. I live in the city and have no vet close by for exotic pets. I read you have to stick your hand inside and put the piglet straight. If there's anyone by any chance here who has pot belly pigs and have had a litter, can you suggest anything? This is the second time she's pregnant. First litter was out within an hour but none survive now this one doenst look normal.
