Exposure to COVID

Yesterday one of my friends asked me If I could go with her for her measurements for her wedding. Today she tested me saying she was exposed a couple pf days ago with COVID. And she did tested today.. She is waiting for results and I just can’t sleep. I am so sad and I been crying non stop. I don’t want anything to happen to my baby😭 I am 16 weeks currently, does anyone had this experience? I feel so bad and so mad with myself. I shouldn’t have gone and stay... Does anyone know how bad this could be? I am getting tested i am just so worried and not for me. For my baby😭😔
