Diana - Conspiracy or real?

I believe in some of the conspiracy theories. Would it be possible that the Royal Family were worried that if Diana was pregnant, or could get pregnant, the father may be a non-Christian? Would they be worried enough to allow people to act? Maybe Diana had served her purpose and given birth to 2 heirs to the Throne? Too many people were chasing the car for no-one to have seen what happened. Where are all the eyewitness accounts?

These are some of the sites available to check on the validity of the claims of conspiracy:
