I just purchased some of these tests, I did one yesterday which was neg and two today at 10.00am and 7.00pm approx. Both of today's tests showed a faint line, especially the first one. But it was very faint! Should I regard this as a positive? Obviously I will test again tomorrow, but I am dying to O as I'm on cd 18. The sooner I O, the sooner we can TTC!!! TIA
