A scope could show pouchitis or a stricture, but probably wouldn’t be able to see a prolapse. This early in pregnancy you’re unlikely to have any issues from the uterus pushing on the pouch. I always skip the sedation for a pouchoscopy, which lets it be no big deal.
Since you’re able to empty your pouch, things aren’t anywhere near grim. A strong probiotic may help things. It sounds like you’ll be fine. You now have some suggestions available in case it gets more difficult. Give your OB a call if you feel like you can’t wait (or if waiting would make you miserable). Remember to breathe.
