Sick/Swollen Tonsils early pregnancy?

Hi all

I am very early in pregnancy and keeping my fingers crossed this baby sticks! Got my first positive 4 days ago and today was actually supposed to be my period so I’m technically 4 weeks today.

Yesterday I noticed my right tonsil/lymph node really bothering me & was sore. Last night I could barely sleep on it. Beyond being exhausted this is the only symptom. Anyone else have issues in early pregnancy? The internet freaks me out bc it’s basically nothing or “tell your doctor now!!”. I’m going in for more blood work today for my second HCG but just wanted to ask here in case anyone else had something similar :)
