HI I have gone through your mail and as you said you are having congestion in your sinuses
and throat with bumps on side of tongue and soreness,considering all these symptoms I am suspecting that primarily you are having infection of your nose and sinuses leading to congestion of nose,nasal obstruction
and discharge.This nasal infection
than spreading to throat and mouth cavity thus causing sore throat
and soreness of tongue,since you are an expecting lady with pregnancy
of three months so you have to go for Culture and sensitivity of throat swab just to know the causative bacteria/viruses and appropriate antibiotic to cure you. If isolated bacteria/virus in culture found harmfull to foetus than that should be properly manage by your gyne doctor/physician.
