No heartbeat

Sierra

Light pink when I use the bathroom nothing in my pantry liner experienced mild to light cramping went to the doctor Friday they did on the stomach and vaginal ultrasound no heart beat was found on either in 9 weeks and 6 days is it too early.. this isn’t my first child! Should I worry my doctor said it may be a miscarriage I agreed to wait to go back on the 7th hopefully the heartbeat will be detectable
