peroid-like spotting right b4 ovulation

I put this in the general post but got no response yet. I am new to the app but I put in my stats and had fertile days up to today. Ovulation is 7/28 but after sex on 7/24 I seemed like my period was starting. its not supposed to start until 8/11. I spotted all day but then it stopped. I can still feel the cramps though...will I still ovulate on 7/28?
