Ovulation cramps?

My last period was July 18th thru 23rd. I've always had cysts every now and then but never has menstrual-like cramps associated with those. I did have sex on July 27th and 29th and he pulled out far enough in advance I didn't worry. But everyday since August 1st I've had menstrual-like cramps. Would you guys say it's most likely from ovulation/ cyst cramps or possible pregnancy cramps? I never have cramps like these unless its a day or two before my period and it's not due.
