The top one is from today bottom one from yesterday and the single one is from September 25th is it just me or is the top one darker than the rest this (I know they are all negative) just not sure if it is to early to BD or if I'm actually fertile since glow says I am. This my first time doing ovulation test so I'm not sure how to tell if I am fertile or not should I keep testing or should I wait a couple days and then start testing again any advice is welcome and baby dust to everyone! ✨✨
