Females can become pregnant 6-48 hours after giving birth, but it's not healthy for a female to be constantly pregnant. I would recommend waiting for one week to two weeks.

you shoudl not put a hamster and a guinea pig in the same cage no matter what.
No, not posible.
Actually rabbits an guinea pigs are fine together. But maybe the female guinea pig is felling lonely being the only kind in the cage. Or maybe its because the rabbit just doesn't like the guinea pig. If it's possible you can try getting another female guinea pig or separating the the guinea pig and rabbits.
Thankfully, female guinea pig don't menstruate.
it is not just the female guinea pig. all guinea pigs need exersise but never ever get a running wheel for the guinea pig their backs are so sensitive.
it depends what type of guinea pig you have
A male desexed Guinea Pig is called "Neutered", and a female desexed Guinea Pig is known as "Spayed".
The male guinea pig is called a boar and the female is a sow because of their name "pig", even though they're not pigs. A male pig is a boar and a female pig is a sow, so the guinea-pigs have been named after them.
Approximately 10 days.
YES and do it fast
