Creamy mucus?

5 days until my period is "due"
Today I have had hot flashes, a three hour long nap & felt nauseous a couple times almost threw up. I even noticed a sensitivity to smell. 
My friend said I had a glow about me yesterday. I'm thinking maybe pregnant? That's what everything said a about the mucus before your period is due. A sign of pregnancy.  I wanted's been 15 days since I know my husband came a little in me. Sorry for the pic it's difficult to see...but it's there...
