Symptoms have subsided

I'm 5 weeks pregnant. I found out a week ago. I had cramps on and off all day and light nausea everyday until now. I still have frequent urination breast tenderness and extreme fatigue. I had a mc in January so I'm very nervous. Anyone had this happen and it was normal and stayed pregnant!? I'm worried about a chemical pregnancy or a mc happening again. I have my first appt on the 2nd.
