Worried!!

Phylisha • I’m 29, married, mother of a daughter in heaven 2/29/16 Penelope Jean and my 2 year old son 5/1/17 Elliott Dean.
I went to the doctor last Wednesday and had labs and my progesterone was at 46 I went in again today and my HCG more than doubled but my progesterone went down to a 44! Should I be worried or is that normal?!
