Pregnant

Question
How long is the girl guinea pig pregnant for a what are some common signs that show that she may be pregnant

Answer
Nika,
The female guinea pig is pregnant for 59-72 days (gestation period)  and they usually have a litter of 1-6 young.
A few minutes after mating a kind of a waxy 'copulation plug' forms to prevent the sperm escaping. The plug is often expelled a few days after mating - you may find this in the bedding. Signs of pregnancy include weight gain, the mother may start drinking more water, and you may be able to feel movement of the babies in the later stages (day 42).
