Thanks for the query.
There is possibility of infection and sometimes that can progress to pelvic infection
As you are having pain, odor etc. better to get examined early.
Two to three hours delay may not cause much difference.
But if you are having fever
etc. better to consult the doctor as early as possible.
Meanwhile clean the local area with luke warm water.
