14 DPO

AF due today according to the app. My ovulation test 14 days back was pretty dark. Until yesterday I was having so many symptoms my boobies hurt, mild headache, no calf pain ( which I usually get after 2-3 days after ovulation, but this time nah). But since today morning I am not seeing any symptoms, I am pretty energetic, normally I get so tired when AF is about to arrive atleast from a week before. What's happening with me?? Planning to test but every day I keep postponing as I am not yet ready to see a negative. My cycles are irregular, it comes from anywhere between 33-40 days, but it comes.
