I'm confused

I tested yesterday for ovulation at 12:45 Pm and it was negative. 👇

I retested today at 5:24 Am still negative. 👇

I got this Light bleeding that lasted 3 or 4 hours the most then completely stopped. (No burning, itchiness or smell down there). 👇

Someone said it could be ovulation bleeding but how if I'm not ovulating? I tested with a pregnancy test and swore i see something but I got line eyes. So what could it be? Yesterdays around 12:45 pm 👇

Today's at 5:24 Am 👇

I'm so confused what is it?
