My fish is swimming upside-down. She also has a huge stomach. Is it possible she's flipping over because she's going to have eggs or is it because she has a swim bladder disorder?

This is a classic sign of swim bladder disorder. Check water quality and chemistry. use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites with nitrates at 20 ppm or less. pH should hover around 7 and water temp should range between 65 F and 72F. Perform a partial water change is necessary to stabilize chemistry and improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Pristine water quality is the foundation for recovery and healing. Next, fast her for 3 days. Resume feeding bits of cooked, shelled green peas until she is swimming and defecating normally. You can fast her one day a week in the future and offer green peas to maintain regularity. If symptoms persist, consider a broad spectrum dewormer and a broad spectrum antibiotic. You can find both in the aquarium section at Petco. Follow label directions carefully and remove the carbon filter insert during treatment in indicated.
