I feel like death

I have been sick for the past few days (coughing, sore throat, sneezing, phlegm, hot flashes, fatigue, some weakness, and headache). I thought I just had a cold but now I’m thinking I might have the flu...

Anyways, I am also on my period (today is the last day). I don’t feel bloated normally other than pre period and the first day or two. Last night/this morning I have felt SUPER bloated and had some minor stomach issues. Does anyone else feel really bloated when they’re sick? And thoughts on if this is just a bad cold or the flu..?
