HELP what to do

So usually my periods are 7 days long ( horrible right.. I know) but this period only lasted like 4 days not complaining but weird .. before my period I had a yeast infection my first EVER. I bought tests just Incase my period was two days late (it was one day late so I wanted to wait another day). But now after my period is over I have sore boobs NOTHING can touch them or I wanna cry. I only get sore boobs right before my period. It never lasts after. Should I test or is that completely off the table?
