There are many reasons you might miss a period. Simple things such as stress or exercising too much can cause a missed period and many girls are irregular during the first few years of menstruating. But if you've missed a few periods, be sure to see your healthcare provider.
Courts usually find probable cause when there is a reasonable basis for believing that a crime may have been committed (for an arrest) or when evidence of the crime is present in the place to be searched (for a search).
Probable cause a standard used at different points in a criminal process â it is the standard used to arrest, the standard used to indict, and the standard used to issue search warrants. In each of these situations, someone might be arrested, indicted (charged), or searched without probable cause being shown.
