fever?

I'm almost 17 weeks and I have had a fever for the past two days on and off, I just went to my obgyn yesterday and everything was good, but after I seemed to get a fever I have no other symptoms of a cold or anything just a fever on and off with a headache that comes and goes too should I be worried? I can't visit that obgyn again as I'm now out of town for two weeks then moving to another state
