No poops is not good, but it does sound like gas. It's important you follow the advice in this thread. If she's acting lethargic and doesn't have any poops, try the baby gas medicine first (if you haven't already), and it that doesn't work in a few hours, she'll probably have to get to thevet. She sounds like she's in pain, and if not treated, it could snowball and get worse.
Keep her moving (even though she doesn't want to) and try and massage her tummy.
Re: the gas meds, brand names depend on where you live, I use Ovol, and depending on the size of the rabbit, they need more than you would give a baby. I've got small rabbits and still give them a half to three-quarters of a dropperful once an hour for up to three hours. (They usually get better after two, though).
Let us know how she's doing!
