What the f*×# is going on with my body

Crystal
My period is aprox 6 days late. Keep getting negatives. My boobs are killing me their so sore. And I have a yeast infection that doesnt seem to want to go away. I am so tires of always getting negatives. Been trying 4 years. Seriously what in the hell is going on. If im not pregnant why is my period late. Im 31. Could it be menopause at my age? ?
