Congested after a miscarriage?

Br
Hello everyone, I am so sorry for all of your losses but we are strong women and God has a plan for all of us!
 I had my first miscarriage on Monday and woke up today very congested. It feels like the start of a cold. I know flu and fever symptoms are signs of an infection but my Vaginal ultrasound and blood work came back looking good and the doctors didn't see any infections. Has anyone felt like this or heard of anyone being congested without a fever after a miscarriage?
