HELP Positive OPK but EWCM drying up

2 days ago I tested my LH surge with clearblue(with smiley edition) but got no smiley at all.. and then the next day(yesterday) I've got so EWCM but I had no time to do an opk test; so today I did a test and it shows up a solid smiley and then I did BD today but I noticed that my EWCM was drying up . Am I too late to do BD? if I test it yesterday will I also get any solid smiley like today? Did I miss my ovulation because I was BDing on the same day my ovulation was occured or is the ovulation goig to start soon? thank you for reading my long questions❤️
