High LH day of period ...??

.

Has anyone had this happen before ? I started my period today, took a what I thought was pregnancy test (it was dark in the bathroom this am and I grabbed it from where I thought the tests were and realized some of my OPKs got mixed when they fell). Well it came back pretty strong, it's not positive but it's reading high LH.... I ended up starting my period a few hours after I took it. But I cant figure out why I would have high LH during my period. I ovulated a few weeks ago ... I have a very very positive test to prove it. Unless... I never actually ovulated? I'm so confused.

Edit. Cycles are regular 32-36 days with peak OPKs anywhere from cd 19-21

Top is my OPK from the 18th, bottom is my OPK from today ..
