stress???

How do know your level of stress in trying to avoid miscarriage. I'm worrying so much as to not stress too much, but how much stress is too much stress? That may seem confusing. But like is everyday life with work and graduate school and a crazy mother-in-law that doesn't know her boundaries too much stress that can cause a miscarriage? I just don't want to worry too much and lose my baby.
