Pinching? Need some insight please🤗🤗

Ok some background. Glow said my ovulation window was the 11-17th. My period is "due" Sunday. I've had weird pinching in my lower right side like right within my hip. But I took a test yesterday and it was a negative. I don't have any other symptoms besides fatigue and maybe itchy boobs(if that's even a real symptom) haha but what could this be?could I still be pregnant?maybe I ovulated later?anyone have any insight?
