Creamy+stretchy cm?

I typically get lots of ewcm about 2 days before ovulation. By the time I get positive opk, which is one day before O, my ewcm decreases in volume and starts turning into creamy cm. By the time I reach O, my cm is usually ewcm mixed with creamy cm. I’m confused as to when should I bd and the highest chance of conception. I’m also trying out EOD this cycle, so I don’t know which days to target. Should I do O-2(lots of ewcm) then O(ewcm+creamy), OR O-3(watery), O-1(ewcm+small amount of creamy) then O+1??

Someone pls help!
