Urine dipstick test shows ph of 7.0 and traces of leukocytes and protein. she prescribed macrobid i went in for loose stools and back and pelvic pain. should i take the medication

No: Trace leucocytes & trace protein are within normal limits & may be simple contaminants such as from vaginal epithelial cells. Presumably nitrite was negative which would have indicated baceria in your urine. Urine culture from a mid stream specimen, separating labia to avoid contamination, after cleansing with soap towlettes, would be more definitative for uti. That way you and your dr. Would know.
