Okay..so I am officially 9 days late..

I am super scared to test! I am testing tomorrow and if that doesn't work, I'm buying one more just go be sure and taking it next Wednesday. I can't wait any longer to take a test! But damn am I nervous! The main symptoms I have had are nausea (at night...idk if that is normal or not), missed period(obviously), using the restroom just a little more than usual, headaches, and little small cramps(but no period). And just to say, I have NEVER been a day late in my life. If I am, then I am about 5 weeks and 1 or 2 days..opinions?
