Would you feel a miscarriage at 16 weeks?

This might be dumb but please hang in there with me. I started bleeding yesterday and went to my OB right away. He did an ultrasound and they couldn’t find where the bleeding was coming from. Baby was moving and the heart rate was 130-150 back and forth. The bleeding has stopped since but today having some slight cramps. His office is closed tomorrow. Just wondering if at 16 weeks pregnant you would feel “different” or feel a miscarriage.
