You know, I was just going to post something very similar. I too, have been testing for OV the past couple of days, and I gather I am probably a bit early in testing, but just don't want to miss it! I think that it can be positive for about 2-3 days?
The line which was next to the control line was a good bit lighter - I assume this is because it is negative? The reason I ask is because there is conflicting info on the pack!
