I have 3 apps that I use to currently track my period and ovulation. I have 2 apps that show the same and one app that shows different. There's not that much of a difference, bit I don't know which one I should go by. I always have sore boobs during my fertile window and I also have sore boobs starting a week bwfore my period... Paying attention to my symptoms is how I usually know which one is more accurate, but this month has been a strange one for sure. I haven't had any sore boobs at all this month. Has anyone had this happen and gotten a BFP??
