i just need to know if it's possible for a pap smear to be wrong? Last year i had a pap and everything was negative except for i had a vaginal infection.I recently went to urgent care because i was having lower back pain and my period was late and still is until this day.But the dr diagnosed me with PID and said its caused by either chlamydia or gonorrhea so she did the cultures and still hasn't called me back yet on my results.Could the cultures from last year get confused with my vaginal infection i had?Or should it been able to detect if i had either STD?Any input would help thank you
