8dpo-LH rising?

I’m new-ish to opk’s & I ovulated last Friday (10/25) which would be aligned to when it usually had predicted my ovulation day. So at 6dpo I had very light pink spotting. Just a tiny amount & only on one bathroom trip. I felt crampy yesterday (like ovulation) so I did an opk and saw it rising a bit. Then this morning I had quite a bit of thick cm (sorry if tmi, like snot) & so I did an opk… my LH is rising again at 8dpo. Is this common before period? Can I ovulate twice? I feel confused by my body now that I’m trying to understand it more while ttc lol
