How do I know my baby is ok?

Kaitlynn • Mommy to my beautiful Makenna ,5. Hubby and I are trying for #2. Recently had a CP. Hoping for our rainbow baby soon!
I've been sick with a cold since January 28. Started a week of antibiotics on Feb 4. Last week I thought I was getting better but a few days ago it hit me again but this time in my chest. I started antibiotics again.  I can't stop coughing and poor baby girl won't stay still. I'm just worried since I don't seem to be getting any better. I'm miserable. 😕
