I have looked on other blogs for pics of other test, and I'm not sure how other kits work - but I have noticed that ppl. are saving the strips and writing the date on them, according the test I am using - you are to dis-guard the test after 5 mins - I'm using the Answer Ovulation 20 strip test kit and those are the instructions. I guess the other gals have different test.
I know something is going on b/c when I first started the test the line was very faint - hardly appeared in the "test" section. This is what the test looked like this week.
Looking at the test - taken at the same time every morning, the "surge" was Tuesday/Wednesday.
