Anyone 😢

Is it normal after a loss to constantly worry about your current pregnancy? I had mc in may and the may before I’m 6 weeks pregnant now and I have my first ultrasound in the morning ... I’m so scared I’m scared I won’t see a heartbeat I’m scared of an empty sac I’m just scared of everyrhing😓I was so happy when I found out but now I’m riddled I’m riddled with stress and worry I feel like I have a gut feeling it’s not gonna work out !!
