Which medicine should I take?

I’m currently out of state and for some reason, urgent care won’t take my insurance card. I feel AWFUL. I’m super nauseous and only had 2 hours of sleep and can’t lay down to get some rest without feeling like I’m gonna barf everywhere. The itchy throat, stopped up nose and everything else isn’t helping. I was around a friend that was diagnosed with type A influenza two days after us hanging out. What can I take that’s over the counter that will help me? Mainly with my nausea? I’m 15 weeks pregnant.
