My guinea pig Coco is about 2 months old. I got her about 3 weeks ago off of craigslist. I was told she was housed with both boy and girl guinea pigs before I got her, so that worried me a little bit. She seems really healthy (she has a big appetite and there doesn't seem to be anything off), but she also has a really round stomach which I can't tell if it's normal or if she might be pregnant (she seems to be growing everyday, but she's still technically a baby, so that's what has me confused). Another reason I'm worried, is that I was holding her today and I felt her stomach move. I have no idea if something else could of caused that or if that could be a baby guinea pig. I am going to try to get a vet appointment as soon as I can, but I just wanted to know if this could possibly be a pregnancy or it's me overreacting and she's just growing. (I will attach a picture of her later.)
