2 days late

Shelby
I'm officially two days late today. Normally before my period I will have back pain, slightly sore boobs and want nothing to do with food. I have had very mild cramps that will come and go. I have also had a weird pain on my left lower abdomen and I have not been able to satisfy my hunger today. I took a test yesterday when I got home from work and it was negative. 
Any thought or advice. 
Thanks
