STIs (Sexually Transmitted Infections).

Trichomoniasis

Trichomoniasis is caused by a microscopic parasite called Trichomonas vaginalis. This results in an infection in the vagina and, sometimes, in the urethra in males. It is typically transmitted sexually.

Vaginal Discharge

The presence of vaginal discharge during the day is not always a sign of an abnormality in the area; instead, it is normal most of the time.
Some of the reasons for the presence of vaginal discharge include:

Non-Infectious
Non-sexually transmitted infections
Sexually transmitted infections

Genital Warts

Genital warts are the most common reason for a visit to the Sexually Transmitted Disease Clinic.
Warts are caused by viruses and generally take about three months to develop from the time of infection.
