Negative pregnancy test positive opk

I'm very confused I took a pregnancy test and all came back negative ! I took an ovulation test and it was blinking , I ovulated on the 16th with a solid smiley face . Now my period is due next week sometime and I'm very confused ! What's going on gals . My ovulation test is positive while my hpt is negative ... Should I use morning pee? I think I took them too early
