Any redness you can see in your frog is probably just the haemoglobin from the bloodworms.
Although there's some controversy amongst fishkeepers about the wisdom of feeding bloodworms, they're only likely to pose a serious threat to small fish that cannot digest or excrete the chitin, which the bloodworms' exoskeleton is made up of. I kept Hymenochirus frogs for around 20 years and never experienced any problems feeding them bloodworms and neither did anyone else I knew personally who kept them.
Don't worry about your frog swallowing stones or sand. It will distinguish what's edible and will expel what's not.
