I have a bad habit of biting my finger nails and sometimes i swallow the nails. can this cause internal bleeding?

No: The chances of this causing internal bleeding approach zero. In theory, the undigested nail could block the opening of the appendix, and cause appendicitis, but this is also unlikely. Probably better to spit them out, or stop altogether. Hope this helps!
