Feelin ill

Last night was horrible! my throat was irritated for d most part of the day yesterday. and it was very hard to fall asleep at night time. I kept burping, my burps were frothy, some were gassy it was just uncomfortable. not sure if i had a fever or not. but i was told my temperature was abit warm. anyways i hope its just a cold or not
UPDATE:
found that it was because of the iron supplement I took, apparently it should not be taken on an empty stomach................
