I feel like I’m dying... so sick

Can anyone suggest to me some good pregnancy safe remedies to help me kick this cold? I’m on day 5. So congested. Feeling horrible. No signs of labor just yet, thank god, but I was due on the 3rd so it could happen any time now. I really don’t want to bring a new baby home when I’m sick. 😔 Been drinking lots of OJ for the vitamin C, hot tea with honey, and I tried Benadryl just incase it was allergy related but it really did nothing except knock me out and make me groggy. I am so desperate to feel better.
