Vaginal secretions may be abnormal or normal. In most cases, this does not mean a problem.

Normal vaginal discharge can be clean, thick or thin, and is generally odorless. The amount and consistency produced can change at different times during the female monthly menstrual cycle.

For example, the greater the ovulation, the thicker and thicker the discharge becomes and the more noticeable it becomes. It may be white at this time.

Due to sexual intercourse and contraception, the amount of your discharge may vary.

Types of vaginal discharge
There are different types of vaginal discharge depending on consistency and color. Changes in the color, quantity or odor of vaginal discharge can indicate problems.
white vaginal secretions can be a sign of infection. If the discharge is stale and looks like cottage cheese, it may be due to a yeast infection.

Yeast infections can also cause vaginal itching and vomiting. This is caused by an overgrowth of fungi called candida (Candida).

A thin, white vaginal discharge with a fishy smell can indicate bacterial vaginosis (BV). BV is the most common vaginal infection in women between 15 and 44 years of age. Other symptoms include urination and itching of the vagina.

In some cases, diagnosis based on vaginal discharge alone is difficult. Other symptoms such as burning, itching, or irritation are often a better sign of the problem.
