A member asked:

What could of caused my daily morning boday basal temperature to drop 1 degree before period is due below 97 degrees?

A doctor has provided 1 answer

Normal: It is normal for your basal body temperature to drop right before your period starts. The trigger for period to start is Progesterone levels falling. It is Progesterone that raises your temperature slightly in the first place.
