Hey y’all! Ovulation question.

Stac

We have been trying to conceive for awhile now, so I’m not a super newbie, but I am a bit confused. Last month (May) my period dragged on a bit longer than usual, mainly spotting and I’m only 5 days after period ended and 4 days away from predicted ovulation. This is my first opk this cycle and it looks super strong already! Could I be ovulating this early? Thanks!
