1st appointment?

When are others being seen for their first appointments?... I’m currently 6weeks and the nurses told me they will set my appointment for when I’m 12 weeks... I explained that I don’t have a regular doctor anymore, that I’m a vegetarian and already low in iron and that it’s my first pregnancy but they still insisted on 12 weeks... just seemed late in the game to me 🤷🏼‍♀️
