Cramping

So I'm due for my period on October 8th, I stopped taking BC back in March due to ovarian cysts and haven't gotten a BFP. I started cramping around 6pm on 9/22 and still am cramping. Feels like AF cramps but could it be a sign of ovulation? Haven't felt cramps before AF has come since before I started taking BC and I find it a bit odd. Any advice is greatly appreciated. Thanx for the love. :)
