Help what does this mean?

Got a positive opk on 8/23, had ewcm 8/21, 8/22, 8/23 and 8/24. Got a temp rise above cover line and it’s stayed up there since. Then 1dpo and 2dpo dry. Now I’m 3dpo and just had a fair amount of ewcm.

Why would I be getting ewcm at 3dpo after being dry? Did I actually not O? Should I bd tonight?
