Get another OB?

How do I know I had a miscarriage and not a SCH?

My ON won’t confirm by ultrasound and I have to wait until next week for more blood work. So how do they know by assuming? What if it’s not a miscarriage? I think an u/s would put me to ease but they don’t seem to be budging with it and have confirmed the miscarriage by over the phone. I wasn’t even seen...

I would be 6 weeks.
