Sick 5 month old.

My 5 month old has a miserable sounding cough, chest rattle and a runny nose that is equally crusty. All around sick.

Between her and my older daughter, age 5 years, they have been consistently sick the past 2 months. 5 year old is immunocompromised and keeps catching everything and my 5 month old catches everything she gets. 🤦🏻‍♀️

I'm waiting on a teledoc appointment and in the meantime I gave her a COVID test. But I cannot tell if I'm seeing a very faint line or just an indent/shadow line.
