Do you wait til its been a week until you ask a dr if things are okay? 
Shes had a small cough here and there for maybe a week but she got a full on cold Friday. Sunday she got a fever and it broke by Monday at 6am but then came back around 10pm. She's had a dry cough, 1st i thought it was a sore throat because when she'd cough and swallow she'd cry. Bt then during the day it wasn't bad... now 4 days later its still dry, she doesn't cry as high pitch like she use to, same when she tried talking. When shes sleeping or laying down and she coughs sometines she coughs and shes okay but most of the time she coughs and it sounds like shes choking. Idk if its because of her runny nose or if she cant breath bc shes coughing. Times she falls asleep with the pacifier in her mouth she coughs and i have to take it out and she still wont breath so i have to tap her back and find ways for her to take a breath... its only been 4 days with a bad cough. Do i have to wait til its been a week to see if this is something more serious or would they be able to check now?
