4 days before expected period and peak?

Hi there, using clearblue digital ovulation test. I am 4 days before my expected period and I am got peak on my test? I had high yesterday

Back story, with my other kids I had high on the teat when I was pregnant before my period. This happened 5x to me.

Today the test is negative ( FR EARLY) but my ovulation stick is peak. I KNOW ov sticks dont detect hcg but it had confused the lh before with hcg for mw personally

Has anyone peaked ovulation / high ovulation right before period? Eager for your experiences…

TIA
