Whats going on?!

Hey guys! Okay so I'm on the pill. I recently switched to a progesterone only pill in July and I have 3 left. Normally I'd be on my AF by now but I'm not. My AF started on sept. 3 and I had sex on the 13th and he came for the first time. I did continue to take the pill as well as plan b. But my period is suppose to be tomorrow and there is no signs of it.
