AF due October 9

Monday 18 i was cramping and I noticed discharge with spotting that made me think I might ovulated early but not sure since I had sex the same day in the morning. But I just took another opk from the ovulation monitor and seems like the 2nd line isn't getting stronger but lighter makes me wonder if I actually ovulated early.

This was Monday discharge

I also had sex yesterday afternoon and my discharge looks like this today
