Answer
White urine is calcium deposit.
This could be due to too many greens. Too many greens can cause bladder stones.

If your guinea pig is lethargic and straining a lot she could have a bladder infection or stones
It is not normal for a GP to be like this.

I cannot tell from your description if she is pregnant or not, but it is advised that you have her checked out by a vet as things are not reading normal. If she is pregnant then you need to know if those babies are ok and she is healthy enough to give birth. if she is in any ill health both her and the babies could die.
If she is not pregnant then she is overweight and this could be going back to the reason her urine is so white. In this case you will have to re-evaluate her diet.
