Leaving work early

Hello! Just to give some context, I’m week two into my training and I work from home. I’m training for my role as a Patients Service Representative for a hospital. This morning I woke up feeling shaky, nauseous and feeling extremely light headed. I’m currently in the middle of my first training session of the day. I literally want to cry because of how sick I feel. Do you think it looks terrible since i’m so new & wanting to reach out to my lead and telling her I need to miss out on the work day because of how sick I feel?
