When to take a test, and the stress!

Soo hoping for a positive when the time comes. 9 days until AF comes(fingers crossed she doesn't ha). I bought the 2 pack First Response tests, and I am trying not to take them too early and go pregnancy test crazy like I do sometimes and stress myself out; but it's so difficult! I just want to know! Why does the wait have to suck so bad? I am trying my hardest to stick to my plan. Take one in a few days, and wait to take the next one if/when I miss my period.

Does anyone else get stressed about the wait and how do you cope with trying not to go PT crazy?
