Hcg rising/No sac

Queline

On September 11, I had blood pouring out of me. Went to the doctor the following day, found out I was pregnant and possibly miscarrying. The doctor could not give me a for sure answer. Since then he has been monitoring my hcg levels and I’ve had 3 ultrasound and an mri. They were not able to see anything but a 6mm cyst.

I am just so confused and feel like it’s taking long for an answer. Has anyone ever had something similar happen?
