Incredibly confused

Eve
My Dr called and said my levels have not dropped. Hgc at 114. It's been 3 weeks since a started to miscarry. I have stopped all bleeding and cramps for a weeks. I even started working out again. So, when she called last night she said she wanted me to go in on Monday for more blood work. If I was in danger she would of ordered an ultrasound right? I don't want it to be an undetected etopic pregnancy. She didn't didn't find anything on 12/30 so I'm so confused.
