Ive been using first response this cycle since it said to start testing for my cycle length...i have had barely there barely pink secind lines. Is that normal? I bought the up and up kit yesterday and it is giving me actual colored lines but its still faint. How well do first response work and do you have to use it really close to ovulation? Anyone stick with up and up and like them? This will be month 4 ttc it took us 9 to get my daughter 3 years ago but we werent tracking. It happened the night of my anniversary :P
