Evaporation lines and my stupidity

I received some very good advice from HW that went along the lines of "don't pee on sticks! It's too early! and sticks are $$$$!". Which is sage and sound advice. And I agreed with her on all points. I then peed on three sticks. THREE.

The first test was used (sounds better than peed on, doesn't it?)(and I mean I used the test, not that it was a used test) Thursday evening. *smack* I was only 7 or 8 days past ovulation.

Mistake number 2: I looked at the test the next morning. I've done this several times. I'm an old pro at digging tests out of the trash can to re-evaluate them and look at them under a brighter light. I've propped a used test up on the toilet tank as a reminder that I'm not pregnant and I should stop peeing on sticks, already. In the year and a half that I've partaken in this obsessive, irrational behavior, I've never ever seen any hint of a possible positive line. EVER. NOT ONCE. Until Friday morning, that is. I then read about evaporation lines and how they can make a test look positive when in fact it is not. Curse them!

Mistake number 3: I peed on another test, naturally. During the appropriate time frame in which to observe results, nothing. Negative. Meh. Fine.

Mistake number 4: I looked at this test when I got home from work. and lo! there was a darker, faint line. Way darker than how the evaporation lines were described. It was a line that would actually show up in a picture. But again. After the prescribed time for reading the test. But, still, this has never happened.

Mistake number 5: Buying more tests.

Mistake number 6: Doing a test Friday night (yes, that's two in one day). You see, the previous two tests were generic HEB brand tests. Clearly they are inferior. I'll try a fancy EPT test. It was negative.

Mistake number 7: Looking at that test this morning. Again. a line.

Why does the Universe mock me?
