Fetal Doppler anxiety

Need someone to help me calm my nerves 😬

I am currently ten weeks tomorrow,, My first ultrasound was last week on Monday at nine weeks and baby was moving around and doing flips in there heart rate was 173 looking good for the nine weeks! I used my home fetal Doppler on the Wednesday after the appointment and found baby’s heart beat within 5 minutes. Now it’s Saturday and I tried just to see and can’t find anything. I’ve had two previous losses at this time and my doctors don’t take phone calls on the weekends. My next appointment is Tuesday but I’m so anxious.
