Very upset!!!

I have 5 days until my c section and I've been so excited to meet my little boy. But I'm pretty sure I'm coming down with a cold 😩😭 I don't want to be sick when my baby is born. This is awful. My daughter is coughing. She's 6 and gets sick often bc she's so friendly with everyone at school ugh! And my fiance has a stuffy nose, not sure what will happen with him considering he NEVER gets sick. I mean seriously. I just got over bronchitis/walking pneumonia and he didn't get sick. Slept in the same bed, kissed me, drank off my cups. What the hell?! Lol. Anyways, I'm just bumming and I don't want to get my baby sick. What should/can i do to shorten this cold? Right now I'm just at the runny/stuffy nose stage with a stomach ache/indigestion. I feel run down and just really blah. Help?
