So I am freaking out with only 4 days till my period

I am having some symptoms My sense of smell has gotten strong and I been staying sick to My stomach. I am fatigued most of the time and I been really dizzy too I crave certain foods. Also today I had white discharge like lotion what else could be wrong

Update!!!! It was a false alarm and I got My period today I feel so stupid and I got My hopes up.
