two week wait is killing me..

I'm driving myself crazy.. every month I swear I'm pregnant and I'm not the symptoms I get are so similar and it drives me crazy.. right now I'm 8dpo and I have sore nipples that can't even be touched, I'm constipated, hungry all the time, have to pee constantly and I just cried my eyes out on a dog commercial... I'm so tempted to test but yet feel it's too early.. anyone else due on the 28?
