Sore throat yellow phlegm runny nose stomache at week 39

I believe this is normal. Cs throut whole pregnancy im always having on and off flu. And now that im 37 weeks, i always get stomach ache every single day with loose stool. Wont hurt to see GP but most prob theyll just ask to eat paracetamol. For blocked nose or runny, can try buy sterimar jose spray. Helps to clear the nose.
