Does this sound like common cold or sinus ? I know I can't be pregnant I just got off my period last month and waiting for this one to come sometime this month and I'm on birth control to let me know. My symptoms are NAUSEA , STUFFY NOSE , MUCUS IN THROAT , AND SOMETIMES DIARRHEA AND A GURGLY STOMACH SOMETIMES THROUGHOUT THE DAY , ALSO A BLOATED STOMACH! Could this be sinus or something else? I'm needing a bit of help ! Thank you !
