HELP!!!

I'm 4 days late on my period. last month I was 6 days the i started. I'm going to wait till I'm 1 week late and test. I really want to be pregnant. My Fiance and I are TTC and really want this. We never use protection or pull out. I really just want to know. I've been cramping not bad though. My breast seems to be bigger to me and my hair is softer, I feel sick sometimes and my bowel movements are changing. Any Advice. it's driving me crazy not to know.
