Hello, I got a guinea pig 2 weeks ago from a pet store. She is about 9 weeks old, and I knew that she may be pregnant since she was living with males as well. Last night I went to go pick her up and I saw blood in her cage, and a couple of fleshy pieces. There was one that was about the size of a kidney bean, which definitely looks as if it could have been a baby, but there was only one that looked like that. Did she have a miscarriage, and should I be concerned about her for any reasons? Please help, I've grown very attatched to this little girl in 2 weeeks. Thanks.
