Is it normal to get a positive OPK during period?!

Lo

I’ll be posting several pictures. My cycles have been very short lately. My last cycle was only 12 days long. I figured I’d test while my period was still flowing to see if maybe I ovulate early to try to catch it. It’s day five of bleeding and I got a positive ovulation test for the first time in five months. Is this normal?
