Me and my boyfriend had sex last night, today it hurts to pee. i've been drinking lots of cranberry over the last few days, could it be a uti or not?

Could be: Some pharmacies have pee sticks. You can dip the stick in the urine and it can tell you if have a possible infection. The best advise is go to the doctor for assessment.

Possibly: Typical symptoms of a UTI are burning with urination often associated with urinary frequency, urgency, voiding small amounts, and occasionally blood. Common after sexual activity. If a uti, may clear with increased fluids though usually 3-5 days of an antibiotic required. Benefits of cranberry juice/capsules controversial. If symptoms persist or worsen, recommend call or be seen by your md.
