This happened with my last baby and I was so stressed about having trouble breathing while in labor. Even though I still had the cold when I did go into labor, it just went away for labor and then returned after I gave birth. I was at the tail end anyway, but it was like my body paused trying to get rid of the virus in order to give birth, then resumed afterward. Our bodies are amazing! Just rest as much as you can so you can fight the cold and all so you'll have energy for labor. I know it's easier said than done when you're feeling yucky. I hope you feel better soon!
