I've never waited until my actual date of my period being due to test, I always tested at least a week to 10 days sooner and any time was pregnant, it showed posotive, sometimes faint but still clear. If you're worried and you're only one week away get a test. To me, it sounds like typical pms, sometimes symptoms are worse than other months. With my most recent pregnancy, I found out when I was 2 1/2 weeks pregnant, pregnancy is USUALLY detected 10 days after conception. Most women don't know that but it's true. So go buy a cheapy test, maybe the $4 Walmart single test, if it's negative, then DON'T test again until you acutally miss your period. Good luck, hope everything turns out for you!
