The only exact way to know is to wait 60-72 days from the potential breeding and see if she has pups. Otherwise sometimes you can gently feel the abdomen for little fluidy lumps, but if you want that done take her to a veterinarian. At later stages in pregnancy your guinea pig's belly will becound very routund and she'll look "light bulb" shaped. X-rays later on in the pregnancy can be done to look for the fetal bones, however I don't think it's worth the risk or cost to do that.
No, not posible.
Yes and fast
YES and do it fast
Approximately 10 days.
no because a female guinea pig needs to be more than 6 months to fall pregnant Yes, the female guinea pig can become pregnant at 2 months so it is possible.
Yes, a veterinarian can perform an ultrasound or X-ray to confirm if a female guinea pig is pregnant. It is not possible to accurately diagnose pregnancy in guinea pigs through physical examination alone.
When I got my guinea pig, we didn't know she was pregnant, so about a month later, my sister got one that wasn't pregnant. It was a little less that a month after that that my guinea pig had 2 babies. During that time, though, Molly, the pregnant guinea pig, was acting very territorial, and Milly, the non pregnant guinea pig, was staying by herself and not having anything to do with Molly. So make sure that if you put a pregnant guinea pig with a non pregnant guinea pig, that the non pregnant guinea pig is a girl, or else there WILL be trouble.
Keep them with a male guinea pig. Be careful because sometime the male with harrass the female.
anything is possible.... watch her carefully
