So confused

My period is due tomorrow but I am not having my normal “I feel like I’m legit dying” symptoms that I have days before I start. Yesterday several people at work literally looked at me and told me I’m pregnant. I didn’t even have the thought that I was until they said something.

I took a pregnancy test as soon as I got home from work yesterday and it was negative - but it was also from a box of cheapo ones.

Normally when my period is about to come my back aches something awful to where I can’t even stand up straight. I have been dizzy all week which is why the people at work told me I was pregnant (which I don’t believe). I have had awful shortness of breath - that they don’t know about. And I have been SO tired lately. All I want to do is sleep. Plus my boobs have been super heavy feeling.. not sore.. just feel heavy - and I’m pretty small.

I had the flu when I thought I was ovulating so unless there was some Devine intervention I highly doubt I am pregnant.. I am trying not to think there’s a chance I could be. But I know my periods coming by my back - and it doesn’t seem like it will be any time soon.
