If the symptoms start to show (those I mentioned above) you will need to have a urinalysis
and culture to determine which bacteria has grown out of
control as well as to determine what antibiotic will be sensitive to it, so it can treat it.
You may also have a yeast infection, which can cause some bleeding to occur during sex. If you have had any thick clumpy whitish vaginal discharge, and some genital itching occur, you would need an anti-fungal treatment.
