Guinea pigs reach their adult weight around eight months of age, and it is for females, on average, 1.5 – 2.5lb. If Coco is 2.6lbs, she likely isn't pregnant. It is never recommend to breed a guinea pig past eight months of age due to the pelvic symphysis fusing. I would not keep her in cage with an intact male guinea pig.
