Miscarriage rate at 11 weeks?

I am 11 weeks pregnant today. I listened to baby’s heart beat on a doppler today and it was 162. I lost it though and was unable to find it after that. Lately I have lost all pregnancy symptoms. No more nausea, no more tender breasts. It scares me so much!

Does anyone know the miscarriage rates at 11 weeks? I want to stop worrying but I can’t 😞
