J.P.
Any fever greater than 101.5 is treated in a hospital and perhaps the MD feels that the temp has not reached that point and is not cause for alarm, however, in the case of being pregnant,it would seem the safest thing to do is to get seen in the ER or Urgent Care if the OB will not fit you in. X-Ray is out of the question, but an ultrasound could be done and a blood count to see if you have a virus or a bacteral infection. Good luck.
