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?

ECheck the water chemistry. The recent water change may have upset it. Use a liquid home test kit or submit a sample for testing to confirm 0 ppm ammonia and nitrites with a 40ppm or less nitrate level. Confirm proper temperature for the species of fish as well. If necessary, another partial water change can be done to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for conditioners include AmQuel Plus, NovAqua and StressCoat. Other options include StressZyme and Prime.
To manage swim bladder issues, withhold food for 2-3 days then feed bits of cooked and shelled green peas. Do this until the fish is swimming and defecating normally. Fast one day a week to maintain regularity.
