Nonexistent appetite

I was pregnant from May until July when I miscarried. I had a huge appetite during that time. I miscarried July 22nd and ever since then I have lost a good 8-10lbs. No exercise, just loss of appetite. I feel ok most days. I am just never hungry. Is this normal? I did a pregnancy test at home and it still had a faint line. Even did a blood test in the doctors office which showed I still have some pregnancy hormones lingering. Is it maybe that they’re going down and that’s why I’m never hungry? I’m not complaining about losing weight, I’m just wondering why my appetite switched up so suddenly and has been this way for almost a month now.
