4 days late, positive opk?

Adrian

According to glow I’m 4 days late with no sign of AF coming soon. Keep getting BFNs on pregnancy tests. Used clear blue advanced OPKs this month and got 10 days of a flashy smiley but never a peak. Took an opk this afternoon on a whim and got this result. Did a digital and got a negative (⭕️). Can someone explain what’s going on? Super confused at this point.
