Late period

Tonya

Ok so this is day 3 and I still don’t have my period. I have all the symptoms, bad cramping, fatigue, low back pain, moodiness everything that usually comes along with my period. I feel like it’s here but every time I go to the bathroom there’s nothing. I never had implantation bleeding, my breasts aren’t sore it all feels like pms without the actual period. I took a test earlier last week and got a BFN. Could this all be psychological? My period is never 3 days late. 1 day if anything. And changing my period on this app changes my ovulation date? Ugh. Was thinking about stopping and getting a test today to make sure.
