Dtd after pos opk

OneandOnly
So do you need to do it for 3 days after positive opk!? I had my positive on Tuesday. Dtd Sunday-Thursday, but now I'm seeing posts saying you should do it for 3 days after positive? I plan to do it again today but am feeling neverous that we didn't do it for 3 days after, we did it day of, 2 days before and 2 days after. What do u guys think?
