Help, possible!?

Noradun • 🌸Due in Sept 2019 with 🌈 after TTC 3.5 yrs with PCOS👣Mommy of 5 💑 Married for 14 yrs👩🏼‍🎓Graduating in 2019 👩🏼‍💻 WFH Mom 🌼

Could someone get a positive opk 4 days before ovulating?? Cervix is SHOW, having EWCM, breasts are killing me, I am bloated, and been cramping all day! 4 days ago I had what might have been a positive opk, it was so close! Starting then I got high fertility on my digital opk too! But since that day my wondfo opks have had no test line! I feel like today is O day, but is that possible without an LH surge, is it possible my surge was 4 days ago?

I also had a temp dip that made me think i was going to O today!
