You may remember my thread about the mysterious pregnancy, the girls are definitely pregnant and I have felt a foot and a sort of extra heartbeat sensation round their tummies, they are very big and I think that since it is 70 days since I had them they were due today. How long should I leave them? They seem slightly off their food but still eating enough but I saw on one guinea pig website that could be a sign of approaching labour. Has anyone had one that has gone on longer than 70 days and was the outcome OK for mum and babies? Thanks in advance
