Newly TTC!

I stopped taking the pill in July after getting AF on the 10th. There was some pretty heavy spotting a couple weeks later, but all testing was negative. August came and I didn't really have a normal AF. Some spotting a couple days here and there. My cycle has been normal my entire life, so I'm not really sure what's going on. I'm waiting for AF any day now.

Is this all just consequence of stopping the pill (which I was on for about a year and a half)?
