Bleeding doc sent me for an ultrasound

Amber

I have been bleeding off an on this whole week and I scheduled an appointment with the physicians assistant because my doc wasn’t available soon enough. She checked my cervix and had me pee on a stick and got a request for an ultrasound later today at 2:30. She also said not to worry and that since I have already heard the heartbeat a miscarriage is less likely. So frustrated. Why didn’t they send me in for a blood test to check my levels or do a heartbeat test? I just feel like she didn’t want to tell me face to face that I am having a miscarriage.
