You : You have a low grade temp, that combined with your symptoms may suggest an acute gastroenteritis (stomach flu). Drink plenty of fluids, rest, and take tylenol (acetaminophen) for your fever. As far as pregnancy is concerned, if you did happen to conceive pn the 4th, you would not be having symptoms at this point, however if there is a possibility you got pregnant before the 4th, then you should take a pregnancy test. If your symptoms get worse or do not improve and your fever increases, see your doctor.

HPT: I don't know how long after sex it was that you developed symptoms. Your could have a viral gastroenteritis. Have you missed a period? Pregnancy is always a possibility after sexual intercourse. If you have missed a period, would recommend a pregnancy test.
