Postpartum symptoms

I’m 3 weeks and 4 days postpartum. I had an emergency c-section. The recovery has been pretty rough. During my second week postpartum I felt a bit better, but since then the past week and a half has been rough. I feel almost flu like symptoms, major body aches, chills, night sweats, feeling feverish (though nothing above 99.7 if anything at all), loss of appetite at certain points in the day...I just feel sick and don’t feel like myself at all. Is this normal?? This is my first child and it’s been extra difficult being forced to quarantine as well. I can’t even go into my doctors office for a postpartum appointment because they’re limiting appointments.
