Covid?

Yesterday I went to the hospital for chest pain. My heart rate was high so they gave me an ekg. I’m pregnant. Then I had to have a ct scan on my chest which really tore me up. But I got to see baby and he’s doing just fine afterwards. I had to do the ct scan for my own health because they suspected a blood clot. They tested me for covid on a rapid test which came back negative. However once they gave me water I started to get really cold, chills, headache and from the thighs down started aching. So once I was released I went home took a shower to relieve the pain. Helped for a few took some Tylenol. Now today I woke up with chills, sore throat, and got really hot. I took my temp which was normal but maybe I have a copy cat fever? Not sure. I was exposed to someone who has and had symptoms starting Sunday with covid. They told me to get tested on Friday pcr but I’m trying to stay calm. Not sure if I have covid or whatever this mysterious illness might be. I really don’t feel good :/
