So confused

I had a chemical pregnancy on July 2nd. The bleeding ended July 6th. I got my peak OPK on the CB digital on Sunday which would have made me CD 17. I’ve been having even more EWCM and tinted yellow snotty like colored CM (no infection for sure) today. I took another OPK tonight just because I was curious, and I got a flashing smiley? I know after your peak you are not supposed to test anymore that cycle but I was confused and afraid the chemical threw things off…. Can a surge of estrogen cause the flashing smiley? I’m just so lost. Cheapie dip stick OPK’s have been near positive but not all the way
