FAIRFIELD, MEHaving seen more students than she can remember come into her office with complaints of nausea and vomiting over the years, Fairfield High School nurse Sarah Bromti told reporters Wednesday shes getting to the point where she can identify morning sickness without much trouble. Ive been at this for a while now, so when a freshman or sophomore walks in during first period with that look on her face, I have a pretty good idea whats going on, said Bromti, noting that most of the time, shes already pulled a teen pregnancy pamphlet out of her desk drawer before the student has even started listing her symptoms. You see enough queasy ones and eventually you can just pick out which arent the flu or food poisoning. If a girl comes in here a month or two after the annual ski trip, thats what it is nine times out of 10. At press time, Bromti had cut her time with reporters short because a pale-looking 15-year-old cheerleader was approaching her desk.
