Anyone with the same symptoms?

I am having the same abdominal cramps on my left side. This is completely unusual for me (never have had cramps before my period). These cramps have been going on since Wednesday of last week. I am also moody, cranky, and extremely tired. I am due my period this Wednesday but when I took a HPT this morning, it was negative. (Its so hard to wait until you actually miss a period to take the test). So I am in the same boat to you! Good luck to you!
