Help!

I know it sounds stupid but it literally started with a severe sore throat which turned into like a 24 hr flu, then a mild cold, then by the end of the first week back to the severe sore throat... along with some nausea. I also never get sick minus a sinus infection when the weather changes 2 times a year. My cat has also been super clingy, and he's never clingy. Also, my boobs are tender to touch (mind you im 4 days before my period but my boobs have never hurt this bad). this test was taken 8 days before my expected period. Not sure whether to believe this or what. What do you ladies think?
