Hello and welcome to HCM
During and after sex it is normal to have an increased vaginal discharge
However, if the discharge is foul smeeling and causes local irritation in the form of itching or sores then it is a sign of infection.
In such a case get the vaginal discharge examined to know if any infectious agents are present.
If it shows bacteria or fungi then treatment is required for your partner as well as you.
It is not expulsion of ovum,
Thanks and take care
