My period is late, my current is going in for 43 days ive taking 5 pregnancy test they are all negative, i dont understand whats happening, i recently got off the pill in may however my period was normal when i stopped until this happened ?

Hormone problem: Apparently from being on the pill, there is an adjustment period for your hormones (estrogen and progesterone) to start regulating again. My guess is that you have too much progesterone and low estrogen levels. Breast tenderness, irregular periods and mood swings-progesterone excess. Now go to gyn to be examined and tested. Always someting unexpected can be the cause but make that appointment.
