Miscarriage with d&c. Still no period 7 weeks

Sam • Dog mom 🐾 Hoping for a rainbow🌈-TTC.

Hi all. I am freaking out. I had a d&c in december. And I was told 6 weeks and all would be well. Started peeing on sticks all positive. Went to the doctor hcg levels at 900. This is soo long after the d&c. It is frustrating and freaking me out at the same time. Has this happened to anyone?
