Why is this happening?

I am 26 days late for my period I didn’t get one last month, my last one was June 23. I am on the pill and have been for the last 6ish months, I take the pill at almost the exact same time everyday and have never ever missed one. I am a virgin the only sexual things I have done was oral and fingering only a few times with my current boyfriend so there is no change of pregnancy. I am due for my period this week and I have gotten all of my usual symptoms and some white discharge, but no period?
