Home Pregnancy Tests

[incomplete]

I know they (IVF clinic) tell you not to but I just can't help myself and I have done a test the last 3 times. This is our 4th transfer and again I did a test. Except this time I did earlier than previously (last 3 times was 2 days before my official test). My official test is this coming Wednesday. I took the test yesterday (Saturday, 4 days before official test) and got a negative. Even though the test I used said it's 99% accurate 5 days before your period is due - do you think I could have done it too early? (I guess I'm looking for a glimmer of hope that it could be wrong).

Part of me is saying it was too early and the other part is saying, it's a negative like the other times (I'm getting cramps like I did the other times, I know Crinone makes me crampy, but these do feel like period cramps, just like the last 3 times and how I get a few days before my period is due).
