Do I have corona virus

I know no one will be able to for sure tell me. But I am just curious. I have a 6 month old. I’m starting to have a bad headache. Like last 2-3 days. Also, my back and neck hurt sooooo bad and I’m tired. Idk if it’s because I’m getting sick or if it’s because I don’t sleep very much with my baby sleeping in bed with me and breastfeeding through out the night and sleeping weird with my arm up around her. Idk what to do
