Falling sick before beta blood test

Was due for blood beta test on 20 Nov 23 and did home pregnancy test showing positive result (abt 3 to 4 weeks). However was feeling abit feverish and mild sore throat and wonder if it will affect the pregnancy. Took 1 paracetamol and trying to use home remedies, hopefully for this feeling to go away. Anyone with such experience and will it affect the fresh pregnancy? Abit upset thinking that things finally work but now sick before the blood test.
