Can anyone help me?

Tasia

Ok so on November 3 I went in and found out at 12 weeks I was miscarrying. Theh found out the baby quit growing st 8 weeks so they had me do a d&c November 5th. I had my first cycle December 8 it lasted 4 days like my typical cycle would. Now I’m 3 dash late with like 6 negative test. Can my hormones still be off? Am I getting false negatives?
