Fever while pregnant 😭

I’ve had a fever on & off for 3 days now, and it won’t stay gone. My body hurts all over (my joints in my hands, my feet, and even my “guts” feel sore). I have a headache that seems to get worse at night, and I’m freaking out. I am calling my OB first thing in the morning, but wanted to know if anyone else has had this. Im 25 weeks and terrified of my baby being affected. 🥺
