Af back so soon?

B

Okay all, I stopped my BC in June. Without it I usually have 2 periods a year, if im lucky. That being said, my june period was on time. My July period arrived at 31 days from the 1st sat of my last period. That was from July 27- July 31. I started bleeding again yesterday. Its mostly brown and the flow isn't as much as a normal one. But I am cramping like the dickens. Anyone else experience this? Or have any idea of what could be going on?
