Positive ovulation test but too late to ovulate

I’ve been cramping since July 2nd I don’t come on till the 13th of July. So I took an ovulation test to see if the cramps I’m feeling are due to that. It’s July 8th and my ovulation test says I’m about to ovulate. However how can that be possible if I’m expected to come on my period on the 13th? Could this mean I’m pregnant?
