Discharge and mucus being emitted from the vagina indicate that your ovulation is about to start. It is common to experience larger amounts of vaginal discharge during ovulation.
During the days preceding ovulation, the production of mucus increases and the fluid becomes clear, watery and yellowish. This period is sometimes referred to as the wet days. Just before ovulation, the fluid becomes stringy. The stringy consistency can be noticed if you take some mucus on your index finger and push your thumb against it, and then slowly separate your thumb from your index finger. You can sometimes see something that is similar to a thin string that runs between your fingers. The string can become 3-6 centimetres long before it breaks. This is a clear indication that the mucus is stringy. On the day of ovulation, the mucus becomes abundant, wet and stringy. A wet feeling in the vagina is also common. Four days after ovulation, there is again less mucus and the dry days begin.
Following ovulation, you will experience vaginal discharge less often and in smaller amounts, and the colour returns to normal or may have a whitish hue. Some women may experience yellowish discharge just before their period starts.
