FEVER in Early Preg

I am in the 1st trimester, it was my 5th week and 6th day on the 14th feb'11 when i started having sore throat and fever (may be because i had an ice cream shake previous night i.e 13th feb) the fever reached 102 degrees F for about a couple of minutes and fluctuated between normal to 100 afterwards. I did take paracetamol on 14th night and 15th morning, the fever was normal then on the 15th feb but in the evening it reached 100 degrees F and i took an antibiotic. Now its 16th feb'11 and i did not have fever today but flu is still present, throat is a bit better now, its my 6th week and 1 day. Is fever considered dangerous for baby's health? What can be done to prevent any complications? What complications can occur? Any one had such experience before and what was the result?
