did I ovulate?

Ilona
Hello. 
DH and I are in our second month TTC. I know we are new to the game, but I'm having some OPK woes and thought someone could shed some light for me. 
This month I started testing with the Clear Blue Digital Ovulation Test. I got my standard couple days of low fertility and started getting my flashing smiley (high fertility) on CD 14. The test says to use FMU so I take it every morning. 
On CD 15&16 I tested in the afternoon as well. Still a flashing smiley. 
CD 17 I did my evening test with a wondfo because I was afraid of running out of CBA test sticks. 99% it was positive. Next morning I got more flashing smileys. 
Today is CD 19. I still have a flashing smiley but my wondfo test is getting lighter and lighter. Is it possible I just missed the surge on the digital? Or did I not ovulate yet? 
DH and I have been BD every day but we are staring to run out of steam. Any advice?
Smiley is flashing and from this morning (CD19)
Wondfos are (in descending order) afternoon of CD17, morning of CD18, afternoon of CD18, and morning of CD19.
