Wearing a ring on the wedding finger is generally not recommended if you are unmarried, as it can be misleading and may send the wrong message.
Wearing a ring on your wedding finger if you are not married is a personal choice, and there are no hard and fast rules against it. However, in many cultures and societies, wearing a ring on the wedding finger can symbolize commitment or intention to get married. It may be misunderstood or misinterpreted by others.
In some cases, wearing a ring on the wedding finger can also be considered bad luck or inappropriate, mainly if the ring is an engagement-style ring traditionally worn by those engaged to be married.
