Please give me advice for having a sick 14 month old

I’m a first time mom and she has never actually been sick since covid happened right after she was born she really hasn’t ever been exposed to anything.

The only place we recently went is the grocery store and it started with a. Runny nose realllly bad and now she’s really congested and crying all the time. She did have a double ear infection a few weeks ago and within a week of the medicine she was better.

I got her ears checked again yesterday just to be sure and they said her ears are fine. But she keeps sticking her fingers in them???

Today she is worse and very congested. I called the on call nurse and she said to hive her warm water and honey, Tylenol and Motrin , and steam from the shower. I feel so bad for my baby. I have done all of that and she is still so congested and crying so much. She finally is asleep after barely sleeping the past 2 nights. I have a sore throat so I’m praying I don’t get any worse because idk how I would get through this I just want to focus on her. I’m also 6 months pregnant :( I’m so stressed. I’m worried they were wrong about her ears. Also I’ve been using the nose suction thing but doesn’t really help.

Any tips or advice ?

They also said if it gets a lot worse then I could get an over the counter cough medicine and decongestant but she is only coughing randomly so idk if I want to do that yet
