Ok it's 9dpo, 10 days past trigger. Yesterday I got a bfn on a dollar tree that, when it dries had a very very very faint line when you tilt it. (Not shown because it's too light to show up) It was with very concentrated SMU. This morning with FMU I got a distinct light line. (Below) but my Wondfos haven't gotten darker (still a barely there line). What do yall think? Could this still be the trigger or maybe moving towards a bfp????
