My guinea pig was with a male. Could she be pregnant after pet store error?

Updated On September 23rd, 2025

Is my guinea pig pregnant? She's about 3 and a half I just got a male guinea pig who is 4 months now who is in a separate cage, but the pet store told me that he was a female and now I've found out that he is a male and they have ran together before but I'm not sure if she pregnant or not.

Unfortunately we cannot diagnose pregnancy without examining a pet in person. If they were always supervised together and you did not see any mating occur then not likely, but if they were unsupervised it is always a possibility. If you want to know for certain a visit to the vet is needed.
