When do you call a doctor?

I got a positive pregnancy test the last 2 days. My last pregnancy I was consistently watched and monitored and eventually referred by my fertility specialist to the MFM docs when pregnancy was confirmed. So I didn’t have to wonder if I was ever pregnant. Now, I’m post partum and not being treated with anyone. How do I know when to call the doctor and get in for blood work or sono ? Thanks ladies ❤️🥰🙏🏽
