Sick husband/immune boosters

Lisa • 🧖🏻‍♀️👨🏻‍🔧👦🏻👶🏻Mama of 2 wife and Aesthetician
So dear old hubby stayed home sick from worker yesterday. I got him some cold and flu medicine. He also confined himself to the family room so he doesn't spread the germs to me. Any suggestions on immune boosters for me?  I feel fine for now. I drink 8oz of oj every morning (that's replaced my coffee).  Is it okay to take those emergenC supplements while pregnant? Anyone else have home remedies or suggestions?
