Ask jinja if a profile exists

How can I check if the object in profile model does not exist in the database, the crearprofile button appears and if it exists, profile appears?

{% if user.profile.is_defined %}
<a class="nav-link" href="{% url 'profile' user.id %}">Perfil</a>
{% else %}                  
<a class="nav-link" href="{% url 'crearprofile' %}">Crear perfil</a>
{% endif %}

enter image description here

class User(models.Model):
    # some fields
    ...

    # some methods
    ...

    @property
    def profile(self):
        try:
            return Profile.objects.get(user=self)
        except:
            return None

{% if user.profile %}
