I originally used the rite aid strips until I ran out and started using the cheaper Amazon brand I had ordered. This morning when I tested with the amazon brand I noticed my line was too light for this stage in my cycle...luckily I had 1 rite aid brand left so I tested that also...and that instantly gave me a positive! This is only my ttc#1 cycle 2..so can anyone with more experience confirm that the rite aid brand is a clear positive please? Thanks!
