Why am i 10days late having my period and why am i having day and night sweats?

Doctor can evaluate: Night sweats are just sweats at night, and day sweats are sweats in the daytime. That means any person with a febrile illness can have fever, chills, and sweats... day or night. Her primary care doctor can check to see if he has one of the common illnesses that cause fevers. If the Dr. doesn't see a common illness nor a pregnancy, more evaluation can be done.
