Please I hope someone can answer asap.

My son has a temp of 102.3
Ive been paranoid of delayed drowning since his shower 2 hours ago. The only time he had water on his face was when I was letting it run down him over his head to wash off soap.
He is already extrmely tired as it is the time he sleeps. Hes exhausted. He's been ..burping alot and swallowing and his stomach gurgling. Idk what to think but I'm anxious. Very anxious. I dont know what the heck too look for. I called 24hr nurseline but they cant give me a diagnosis and just told me the only way to know is if i go to ER. Although she didnt tell me to go...just the only way to get a diagnosis and check for water is by a doctor.
