First month using OPK - help!

Hi everyone - so this is my first month using ovulation tests. I did clear blue digital from CD8 to CD13. I got flashing smileys on CD9 to CD12. On CD13 I got the solid smiley for peak day. We DTD on peak day and once during the flashing smiley days. Today (CD14) I did an opk strip test (see pic). Does this mean I am still in fertile window and we should keep DTD. This is first time I am trying to understand my cycle in this way....any advice appreciated!
