For how much days up to a menses the rectal temperature should decrease? Whether and if she decreases, is it a sign of pregnancy or there can be other reason?

[Pasenjuk A.M.]

For 1 3 days. The raised or increased rectal temperature not always a sign of pregnancy because there can be an inflammatory process in a small basin or is raised or increased the general or common body temperature.
