I really thought I was

I really thought I was pregnant. First I had light cramping 2 and a half weeks ago. A lot of bloating! A lot of nausous, a lot of high smell, loss of appetite. Then my period was due on November 15. Didn't come. And the day I was gonna test [today November 18] I ended up waking up with AF. I really just feel like crawling in a corner now.
