OCD with the tests

Seriously, I am ridiculous. I bought three First Response Tests while picking up the Pledge thingamobob. Of course, as I am only 6 days past when I assume I ovulated.....it would only be stupid of me to take a test at this point....but I did anyway. My reasoning...."well, it's just 4 dollars for that ONE test, and I didn't buy a mocha today....sooooooo alright!" The first day I really should test is MAYBE March 31st. So 4 days to go....and in my infinite wisdom and craziness, I may be out of tests by then!
