Question about opks

Question!

After I get a positive opk and get a negative opk does this mean Ive already ovulated or am I still going to ovulate soon?

I took two strips a day to make sure I was in my LH surge and bd every night for the past 5 days. My first positive opk was on sunday until tuesday it was negative.

Am I in the clear or am I going to ovulate within the next 12-48 hrs? Im so confused and bummed because I didn’t bd last night because I thought i was done ovulating.

I’m only using opks and preseed.
