Is it safe to have sex with my wife, she's five-weeks pregnant and she spotting?

Possibly: Spotting is pretty typical at that point in pregnancy, but if she is having any cramping or heavy bleeding, she needs to be seen. That said, if she were to miscarry at 5 weeks, there is essentially nothing that could, or should be done about it. Make sure she is taking her vitamins, and keep track of the spotting. If it gets heavy, have her see her gynecologist.

Hold it: Spotting may be nothing, but get an ok from her gyn please.
