Worried!

My first appointment was Monday morning. So they did blood work and all that. The drs office just called and I missed it. I don’t have good cell service at home so usually when Someone leaves a voicemail I won’t get it until I go out which won’t be until tomorrow. They called at 4:58 and close at 5 so of course when I call back they are closed! Now I’m freaking out because I’m worried something is wrong
