I've been sick since Friday, called off work today. Saturday went to a walk in clinic and they said I have an upper respiratory infection but prescribed me nothing. Went to my allergist today and she gave me an antibiotic (category b, safe during  pregnancy) and told me to take it in a few days if it doesn't get better. I'm not sure if I should just take it now or wait. I'm afraid I'll get worse and I already feel horrible and have been in bed since Friday after work. She wanted to give me steroids cause it's so bad but she can't due to pregnancy (or it would be last resort). What do y'all think. Should I just take the meds now or wait?
