Still trying to get the hang of CM..can someone help me

I had EWCM on Monday and Tuesday. I got a positive opk on Tuesday my app says ovulation was yesterday which would match with my opk. Today(Thursday) I have watery CM...does this mean my still fertile or that I have ovulated already?

I BD on Sunday Monday and Wednesday so just wondering if I should do it again tonight? (I won’t get home until late so thinking I may miss the egg timeline)

TIA
